This course will consider a range of mostly nonlinear partial differential equations, including elliptic and parabolic PDE, as well as hyperbolic and other nonlinear wave equations. In order to study these equations, we will develop a variety of methods, including variational techniques, and fixed point theorems.  One important theme will be the relationship between variational questions, such as critical Sobolev exponents, and issues related to nonlinear evolution equations, such as finite-time blowup of solutions and/or long-time asymptotics.

The prerequisites for the course include familiarity with Sobolev and other function spaces, and in particular with fundamental embedding and compactness theorems.

Other topics in PDE will also be discussed.

The course will survey the branch of mathematics developed (in its abstract form) primarily in the twentieth century and referred to variously as functional analysis, linear operators in Hilbert space, and operator algebras, among other names (for instance, more recently, to reflect the rapidly increasing scope of the subject, the phrase non-commutative geometry has been introduced). The intention will be to discuss a number of the topics in Pedersen's textbook Analysis Now. Students will be encouraged to lecture on some of the material, and also to work through some of the exercises in the textbook (or in the suggested reference books).

Elementary analysis and linear algebra (including the spectral theorem for self-adjoint matrices).

The theory of operator algebras was begun by John von Neumann eighty years ago. In one of the most important innovations of this theory, von Neumann and Murray introduced a notion of equivalence of projections in a self-adjoint algebra (*-algebra) of Hilbert space operators that was compatible with addition of orthogonal projections (also in matrix algebras over the algebra), and so gave rise to an abelian semigroup, now referred to as the Murray-von Neumann semigroup. 

Later, Grothendieck in geometry, Atiyah and Hirzebruch in topology, and Serre in the setting of arbitrary rings (pertinent for instance for number theory), considered similar constructions. The enveloping group of the semigroup considered in each of these settings is now referred to as the K-group (Grothendieck's terminology), or as the Grothendieck group.

Among the many indications of the depth of this construction was the discovery of Atiyah and Hirzebruch that Bott periodicity could be expressed in a simple way using the K-group. Also, Atiyah and Singer famously showed that K-theory was important in connection with the Fredholm index. Partly because of these developments, K-theory very soon became important again in the theory of operator algebras. (And in turn, operator algebras became increasingly important in other branches of mathematics.)

The purpose of this course is to give a general, elementary, introduction to the ideas of K-theory in the operator algebra context. (Very briefly, K-theory generalizes the notion of dimension of a vector space.)

The course will begin with a description of the method (K-theoretical in spirit) used by Murray and von Neumann to give a rough initial classication of von Neumann algebras (into types I, II, and III). It will centre around the relatively recent use of K-theory to study Bratteli's approximately finite-dimensional C*-algebras---both to classify them (a result that can be formulated and proved purely algebraically), and to prove that the class of these C*-algebras---what Bratteli called AF algebras---is closed under passing to extensions (a result that uses the Bott periodicity feature of K-theory).

Students will be encouraged to prepare oral or written reports on various subjects related to the course, including basic theory and applications.

An attempt will be made to supply the necessary prerequisites when needed (rather few, beyond just elementary algebra and analysis).

A surface moving so as to decrease its area most efficiently is said to evolve by mean curvature flow. Mean curvature flow is the most natural evolution equation in extrinsic geometry, and shares many features with Hamilton's Ricci flow from intrinsic geometry. Mean curvature flow and its variants have many striking applications in geometry, topology, material science, image processing and general relativity. 

In this course we will provide a general introduction to mean curvature flow and some of its applications. In the first half of the course we will focus on the evolution up to the first singular time, which can be described in the classical framework of smooth differential geometry and partial differential equations. A central challenge is then to extend the solutions beyond the first singular time and to analyze the structure of singularities. This is crucial for the most striking applications, and will be our focus for the second half of the course.

Some basic background in geometry is required, i.e. you should be familiar with basic concepts such as surfaces, manifolds, Riemannian metrics and the second fundamental form. Some prior knowledge of PDEs is also helpful, but not strictly required.

The aim of the course will be to give a modern treatment of the classification of finite subgroups of various linear groups such as SO(3), O(3), SU(2), GL(2,C), their projective counterparts, and of some related arithmetic groups such as GL(2,Z), SL(2,Z). Especially a comprehensive classification of the finite subgroups of GL(2,C) is surprisingly difficult to find in the literature, but recent developments in Singularity Theory, such as the McKay correspondence, allow for a very succinct and "visual" classification.

Mathematical tools to be developed:
Some Euclidean and spherical geometry,
Root systems and reflection groups,
Linear representation theory of groups,
Geometry and algebra of quaternions,
Clifford Algebras and Pin and Spin groups.
The McKay Correspondence and Coxeter-Dynkin diagrams,
Goursat's Lemma for subgroups of products.

The principle of functoriality was introduced by Langlands as a conjecture in 1970. It is the fundamental pillar of the Langlands program, and as such, will have enormous implications for number theory and representation theory. However, we are still a long way from any general proof.

Langlands later (around 2000) made an extended proposal, which he called Beyond Endoscopy, for using the trace formula to attack the functoriality conjecture. The proposal will not be easy to carry out- it will probably require the efforts of many people- but it has already led to new questions that are very interesting in their own right.

The course will be an introduction to Beyond Endoscopy. There is as yet no monograph on the subject, but I shall nonetheless attempt to give a broad overview on the trace formula, and how it is expected to relate eventually to functoriality.


Core courses in analysis and algebra or their equivalents, basic theory of Lie (and/or algebraic groups), and perhaps also a course in algebraic or analytic number theory. The course will be a natural successor to this year's course MAT1197HS on the trace formula and last year's course MATH1196HS on representations of real groups, but in general, I will try to be flexible about prerequisites.

This course will provide a basic introduction to the theory of Shimura varieties. The classical modular curves are quotients $\Gamma\back \H$ of the upper half plane

$$\H = \{ z = x+iy\mid y>0\}$$

by subgroups $\Gamma\subset \SL_2(\Z)$ of finite index. Their rich number theoretic content arises from the fact that they can be viewed as moduli space of elliptic curves with some additional structure. In particular, they and various line bundles over them can be defined over number fields, i.e., have 'canonical models'. This fact provides fundamental rationality properties of modular forms, the sections of such bundles, and these, in turn,
have many important arithmetic applications, for example to the special values of L-functions.

Classical generalizations of the modular curves include Hilbert modular surfaces, Siegel modular varieties, complex ball quotients, etc., and, as complex manifolds,  all have the form

$$\Gamma\back D$$

where $D$ is a bounded hermitian domain associated to a reductive group $G$ and $\Gamma\subset G$ is an arithmetic subgroup. By a result of Baily-Borel $\Gamma\back D$ is the set of complex points of an algebraic variety defined over $\C$.  The theory of Shimura varieties provides a beautiful and deep description of the arithmetic aspects of such varieties and the vector bundles over them.  Because of their 'explicit' construction and connection with automorphic forms, such varieties provide a fruitful testing ground for many conjectures about the arithmetic of algebraic varieties which are generally inaccessible. Moreover, the Langlands program and conjectural theory of motives suggest that Shimura varieties should be, in some sense, universal.
For example, every elliptic curve over $\Q$ arises from a modular curve.  

Topics will include:
 - modular curves as moduli space for elliptic curves
 - basic facts about abelian varieties and period matrices
 - Siegel modular varieties
 - hermitian symmetric domains
 - arithmetic groups
 - locally symmetric varieties and the Baily-Borel theorem
 - Hodge structures
 - period domains
 - moduli spaces of abelian varieties
 - examples, PEL Shimura varieties
- complex multiplication
- canonical models
- Deligne's formulation
- Hodge type Shimura varieties
- automorphic vector bundles
- arithmetic automorphic forms

Some of the most basic objects of study in Connes's non-commutative geometry---for instance, the non-commutative tori---will be considered from an elementary point of view. In particular, various aspects of the structure and classication of these objects will be studied, and a comparison made between the properties of these objects and the properties of the underlying geometrical systems. Some indication will be given of their use in index theory.

Lie groupoids, and their infinitesimal counterparts, the Lie algebroids, arise in many areas of differential geometry, such a Poisson geometry, index theory, foliation theory, or symmetries of differential equations. In recent years, there has been a lot of progress towards understanding these structures, such as the Crainic-Fernandes integrability obstructions and various results on 'multiplicative structures' on Lie groupoids.

Tentative topics include:

1. Lie groupoids: Definitions, examples, basic properties

2. Lie algebroids: Definitions, examples, basic properties

3. The Crainic-Fernandes theorem

4. Cohomology of Lie groupods and Lie algebroids, van Est map

This is a continuation of the course "Hyperbolic surfaces" offered in fall 2017 by Maxime Fortier Bourque. It goes somewhat deeper into the study of deformation theory of hyperbolic structures on surfaces. As a first goal, we will cover the recent paper of Mirzakhani "Counting Mapping Class group orbits on hyperbolic surfaces". We start with the needed background material such as, geodesic currents, Thurston measure on PML, Weil-Petersson symplectic form and Thurston metric on Teichmüller space and then cover the basic arguments of the paper. We then discuss some implications and related results including some counting problems in Teichmüller space.

Basic hyperbolic geometry and some familiarity with Teichmüller space.

This will be a descriptive set theory course specializing on recent connections between descriptive set theory and certain areas of Ramsey theory and topological dynamics. We will explore first the close connections between the theory of computations of Ramsey degrees on one side and the representation theory of universal minimal flows of topological groups on the other. Then we will study dynamics of isometry groups and its close relationship with the approximate Ramsey property of finite metric structures. If time permits, we will apply this theory and give a representation of the universal minimal flow of the group of affine homeomorphisms of the Poulsen simplex and other related metric structures.

This course is an introduction to the active research areas surrounding optimal transportation and its deep connections to problems in geometry, physics, and nonlinear partial differential equations.The basic problem is to find the most efficient structure linking two continuous distributions of mass --- think of pairing a cloud of electrons with a cloud of positrons so as to minimize average distance to annihilation.

Applications include existence, uniqueness, and regularity of surfaces with prescribed Gauss curvature (the underlying PDE is Monge-Amp\'ere), geometric inequalities with sharp constants, periodic orbits for dynamical systems, long time asymptotics in kinetic theory and nonlinear diffusion, and the geometry of fluid motion (Euler's equation and approximations appropriate to atmospheric, oceanic, damped and porous medium flows). The course builds on a background in analysis, including measure theory, but will develop elements as needed from the calculus of variations, game theory, differential equations, dynamical systems and fluid mechanics, not to mention physics, economics, and geometry. A particular goal will be to expose the developing theories of curvature and dimension in metric-measure geometry, which provides a framework for adapting powerful ideas from Riemannian geometry to non-smooth settings which arise both naturally in applications, and as limits of smooth problems.

In this course we  study partial differential equations appearing in physics, material sciences, biology, geometry,  and engineering. We will touch upon questions of existence, long-time behaviour, formation of singularities, pattern formation. We will also address questions of existence of static, traveling wave, self-similar, topological and localized solutions and their stability.

Specifically we consider Allen-Cahn equation (material science), Ginzburg-Landau equation (condensed matter physics -superfluidity and superconductivity ), Cahn-Hilliard (material science, biology), Mean curvature flow and the equation for minimal and self-similar surfaces (geometry, material sciences), Fisher-Kolmogorov-Petrovskii-Piskunov (combustion theory, biology), Keller-Segel equations (biology), Gross-Pitaevskii equation (Bose-Einstein condensation) and Chern-Simmons equations (particle physics and quantum Hall effect).

The course will be relatively self-contained, but familiarity with elementary ordinary and partial differential equations and Fourier analysis will be assumed.

Elementary ordinary and partial differential equations, Fourier analysis, Elementary analysis and theory of functions or physics equivalent of these.

General Relativity is a geometric theory proposed by Einstein in 1915 as a unified theory of space, time and gravitation. It describes the evolution of gravitational physical systems such as planetary systems, galaxies, black holes and ultimately the universe as a whole. 

This course will strive in a very intuitive, but still rigorous, way to uncover the subtle connections of Einstein's theory with geometry and analysis. We will prove purely mathematical theorems which have direct consequences for fundamental phenomena of our natural world. Moreover, this course will provide students with the background needed for studying recent research papers in the field and for initiating their own research projects. 

The following topics will be covered:

A. Geometry: Introduction to Riemannian, Lorentzian and Null geometry,
B. Einstein equations and fundamental predictions: gravitational waves, black holes, trapped surfaces,
     Penrose incompleteness theorem
C. Black hole dynamics: Schwarzschild and Kerr families  

Some familiarity with basic differential or Riemannian geometry is desirable but not required. All students should be familiar with advanced multivariable calculus.

We will mainly follow the lecturer's ''Lecture notes on general relativity'' (available online).
Robert Wald's "General relativity",
Hawking and Ellis' ''The large scale structure of spacetime''.

The goal of this course is to explain key concepts of Quantum Mechanics and to arrive quickly to some topics which are at the forefront of active research. In particular we will present an introduction to quantum information theory, which has witnessed an explosion of research in the last decade and which involves some nice mathematics. 

We will try to be as self-contained as possible and rigorous whenever the rigour is instructive. Whenever the rigorous treatment is prohibitively time-consuming we give an idea of the proof, if such exists, and/or explain the mathematics involved without providing all the details.

* Some familiarity with elementary ordinary and partial differential equations
* Knowledge of elementary theory of functions and operators would be helpful

Syllabus (not all topics would be covered):
* Schroedinger equation
* Quantum observables
* Spectrum and evolution
* Atoms and molecules
* Density matrix and open systems
* Quasiclassical asymptotics
* Perturbation theory
* Adiabatic theory and Berry phase
* Self-consistent approximations
* Bose-Einstein condensation
* Open systems and Lindblad evolution
* Quantum entropy
* Quantum channels and information processing
* Quantum Shannon theoroms

Yes, we all dream of the day we will prove that powerful theorem, whose beauty and sophistication will leave our colleagues breathless.  It will, of course, be a product or pure thought, affirming that our intellect rises far, oh so far, beyond everybody else's. Obviously, no computers will be used. We are artists and philosophers, not technicians.

As a temporary measure I have learned to work with computers, and I plan to share what I have learned with you. For me, computer-assisted mathematics is a powered exoskeleton (seen Avatar?  Iron Man?) for the brain. It's still my inner powers that everybody should admire, yet they reach much farther now that I've learned how to integrate them so tightly with the machine. Learn that too and reach far! I often use the platform "Mathematica" (though not only), and hence that's what I'll teach (though perhaps not only).

About one third of the course will be a systematic overview of Mathematica following that or another textbook. The other two thirds will be divided into chapters, each about some (mathematical) real life problem that I have at some point encountered and solved with computers.  The typical chapter will start with a mathematical introduction (sometimes deep and meaningful in itself). I will then pose a computational problem, and challenge you to solve it better than the solution that I found and will present a week or two later.  Many (though not all) of the problems will involve algebraic computations in knot theory, as this is what I know best. There will also be graphics, and some interaction with the web and with TeX.

This course is designed to provide upper level undergraduates and beginning graduate students with an understanding of how mathematical modeling is the link between mathematics and the rest of the world. Nature is highly complex and mathematical modeling can help to unlock the secrets to problems in engineering, physics, astronomy, biology, medicine, chemistry, economics, and the social sciences among other fields. Modeling is a way of structuring questions about the world so that mathematical techniques may provide insight. It is as much an art as a science.

This course will cover a broad spectrum of modeling approaches including optimization, dynamical systems, and stochastic processes. Some topics covered include sensitivity analysis, model robustness, multi-variable optimization, linear programming, operations research, compartment models, neuronal models, bifurcation theory, renewal theory, Markov chains, queuing theory, diffusion, and some stochastic models in biology. Regular computer lab sessions will be used to teach visualization and simulation of the mathematical models studied.

A substantial component of the course grade will be a modeling project with a student-selected topic. Evaluation of the project will be based on a research report and a presentation. Regular written homework and two midterm exams will also be part of the course grade.

In order to be successful in this course, it will be necessary to have a solid foundation in ordinary differential equations (MAT244) and linear algebra (MAT223,MAT224). A course in probability or some experience with Matlab or Python would be helpful.

We are planning to study the theory of dynamical systems in one complex variable.

The theory of iterations of polynomial maps on the plane goes back to the works of Julia and Fatou at the beginning of the 20th century, but it did not fully flourish until the 1980s with the introduction of computer simulations and the works of Douady, Hubbard, Sullivan, Thurston, Milnor, Lyubich, and several others. We will investigate the dynamical properties of iterations of polynomials and rational maps on the plane and discuss their classification and their parameter space.

The subject is by now classical, but still full of research questions. We will approach the topic from the beginning, assuming only fundamental knowledge of complex analysis and topology as provided by the core courses. Towards the end, we will also discuss the theory of entropy for real and complex polynomials, a topic I work on and which has been recently revisited by Thurston and still deserves to be fully explored. Topics

    • Riemann surfaces and the Poincare' metric.
    • The Julia set and the Fatou set.
    • Local fixed point theory.
    • Global fixed point theory.
    • Structure of the Fatou set.
    • Caratheodory theory and local connectivity.
    • The Mandelbrot set.
    • Combinatorial dynamics.
    • Kneading theory.
    • Entropy of unimodal maps.
    • Hubbard trees.
    • Core entropy.

Minimal surfaces are solutions of the most basic variational problem in submanifold theory, that of extremizing the area. These surfaces have been intensely studied for the past 250 years and have found striking applications in other fields of mathematics. We plan to discuss the basic variational theory of these objects, including the questions of existence and regularity. We will talk about unstable minimal surfaces obtained by min-max methods and their recent impact on the field. This includes in particular the solution to the Willmore Conjecture (1965).

Evolution equations arising in the modelling of life science problems is a fascinating subject area. It is at the very heart of the understanding of many important problems arising in biology, medicine, ecology, physics and mechanics. The goal of this course is to convince the audience of this and to show the important role of applying mathematics to real world situations, and explain, in particular, experimental findings.

I hope that this course will create additional interest in life-science problems among young researchers. Moreover, we aim to show how modelling real world situations (life science problems) has a crucial impact on mathematics, creating new challenging situations for mathematics itself, in particular for infinite-dimensional dynamical systems and their attractors.

We will present an elementary introduction to the revolutionary and important new theory of Compressed Sensing. We will fill in the basic mathematical prerequisites on Fourier Transforms and Wavelets. Other topics will depend on the interests of the class: we will choose between a detailed explanation of how MRI works, imaging electric properties of tissue, or present modern techniques in signal processing for denoising, segmentation and registration.

Students requiring individual instruction in mathematical topics should consult with the Mathematics Graduate Office.
