640:507 Functional Analysis R. Nussbaum HLL 425 MW 6; 4:305:50
We will begin with basic results about Banach Spaces: the Baire category theorem, the uniform boundedness theorem, the open mapping and closed graph theorems, and many variants of the HahnBanach theorem. We will discuss general bounded linear operators on Banach spaces and the theory of compact linear operators. Other topics will include weak and weak* topologies on Banach spaces, reflexive Banach spaces, Hilbert space and compact selfadjoint or normal operators on Hilbert space. Generally speaking, all topics will be illustrated by applications in analysis, e.g., to integral or differential equations. Some excursions to nonlinear techniques (e.g., the Schauder fixed point theorem) and their applications will be made.
640:509 Sel Topics in Analysis S. Gindikin HLL 525 TTh 5; 2:504:10
The Radon transform has broad connections and applications inside mathematics: differential equations, harmonic analysis, analysis on homogeneous manifolds, representations of Lie groups, complex analysis. There are interesting discrete versions of the Radon transform on trees and buildings. On the other hand, the Radon transform is also the mathematical basis of tomography. I want to discuss in this course both sides of the Radon transform and its generalizations. We will not go into numerical problems of tomography but it is quite instructive to consider some purely mathematical problems which appear in modern tomography. The focus will be on specific examples and formulas.
We will need basic knowledge of mathematical analysis. I will distribute fragments of a book which will soon be published by American Mathematical Society.
640:517 Partial Diff Equations Z. Han HLL 425 MW 4; 1:102:30
This is the first half of a yearlong graduate course on PDE. In this first course, the aim is to introduce some of the fundamental issues in the study of PDE's: the correct posting of boundary value problems or initial value problems for different kinds of equations, the main features for solutions of each kind of equations, the necessity and the correct use of a variety of function spaces, and the importance of a priori estimates for solutions. I plan to discuss these issues in the context of the prototype equations: the Laplace equation, the D'Alembert wave equation, and the heat equations. Explicit representations of solutions will be used for these prototype equations, but the aim of the course goes beyond this: after the introductory material, I will discuss how to extend these methods, or introduce new methods, to deal with these issues in more complex settings, where the coefficients may be variable or the equation may be nonlinear. Topics to be discussed include: the concept of characteristics, solutions of first order nonlinear differential equations, Fourier's method for discussing Cauchy problem of constant coefficient equations, the method of freezing coefficients to deal with perturbations of prototype equations, and introduction of nonperturbative methods, such as variational methods, or energy estimates for wavetype equations. I will place certain emphasis on illustrating the use of the methods in a variety of settings, leaving some detailed development of the theory and derivations of some estimates to the second semester.
The prerequisite for this course is a strong background on advanced calculus involving multivariables (esp. Green's Theorem and Divergence Theorem), the theory of ordinary differential equations(ODEs), and basic properties of Fourier transforms. Towards the latter part of the course, more background is needed: $L^p$ function spaces and the usual integral inequalities. These topics are covered in the first semester graduate real variable course. For physics/engineering graduate students interested in this course, it is possible to follow this course, if your background in the prerequisite area is particularly strong and you are willing to accept a few facts from Lebesgue integration theory and to learn the use of integral inequalities.
The text proposed for this course is Partial Differential Equations by Lawrence C. Evans, published by AMS, 2002.
This course does not assume the students have had a PDE course at the undergraduate level. For students without any prior experience with PDEs, it will be helpful for you to do some advance reading of the first five chapters of the text Partial Differential Equations: An Introduction by Walter Strauss, publised by John Wiley & Sons (1992), ISBN# 0471548685, and use it concurrently with our required text as supplemental reading.
640:519
Sel Topics in Diff Equations
S. Chanillo
HLL 423 TF 2; 9:5011:10
Prerequisites: Math 501, 502 and 503. Knowledge of implicit and inverse
function theorems.
Text: There is no text book for the course, but R. Osserman's book
on Minimal Surfaces is a good source.
Course Outline: The course will study Minimal surfaces. We will cover basic topics like the Weierstrass representation, Bernstein theorem and the Heinz curvature estimate. Then we will solve the Plateau problem in some form. We will also prove the monotonicity formula for minimal surfaces. Time permitting we will try to get into some geometric measure theory.
640:541 Intro Alg Topology (II) P. Landweber HLL 525 TTh 4; 1:102:30
This course will be a sequel to Math 540 being taught by Prof. Luo in Spring 2003, but can also be viewed as a mostly independent course on cohomology and homotopy theory for students who already have had an introduction to homology.
The text will be Allen Hatcher's excellent new book
Algebraic Topology, available for $30 in paperback from
Cambridge University Press, as well as
online here
The plan is to start by covering some preliminary notions in
Chapter 0 and reviewing the definition and main features of
homology in Chapter 2. We will then cover Chapter 3 on cohomology
in detail, including a selection of additional topics at the end
of the chapter (such as Hspaces and Hopf algebras); there are
features to cohomology that are not present in homology. We will
end by covering basic results on homotopy groups in Chapter 4,
aiming to reach the long exact sequence of homotopy groups for a
fiber bundle, and to then study homotopy groups of classical
groups as well as the cohomology of fiber bundles.
Note: The basics of cohomology theory can be found in Jim Vick's book Homology Theory. Hatcher's book gives many more examples, exercises, and additional topics on cohomology, and also gives a thorough treatment of homotopy theory with a large collection of additional topics.
640:547 Topology of Manifolds F. Luo HLL 525 MTh 3; 11:3012:50
This is an introduction to topology and geometry of 3manifolds with emphasis on the geometric aspect of the theory. More specifically, we will focus on the Ricci flow program of Richard Hamilton toward resolving the geometrization conjecture in dimension 3. Very recently (Nov. 2002), Grisha Perelman made a major progress on the Ricci flow program. He also claimed to have a proof of the geometrization conjecture (especially the 3dimensional Poincare conjecture) in March 2003. Our goal in the course is to understand the basics of Ricci flow on surfaces and 3manifolds.
Here is a sketch of what we are planning to cover.
(1) The work of Hamilton on the classification of
3manifolds with positive Ricci curvature.
(2) The work of Hamilton on singularity formations in
Ricci flow.
(3) An introduction to Perelman’s work toward a
solution of the Geometrization conjecture.
This course is intended to be selfcontained. The students should know basic topology (manifolds and covering spaces). Some knowledge of differential geometry will be helpful but not necessary. We will give a rapid introduction to Riemannian geometry at the beginning of the course with emphasis on tensor calculation.
The tentative meeting time will be MTH3. But that can be changed. For more information, please send an email to fluo@math.

640:560 Homological Algebra Y.Z. Huang HLL 423 MW 4; 1:102:30
The theory of tensor categories has recently become an important tool in the study of a number of mathematical and physical problems. The fundamental connections among quantum groups, knot and threedimensional invariants and conformal field theories are best understood through ``modular'' tensor categories. Many classical algebraic notions, for examples, associative algebras and Frobenius algebras, have generalizations in the framework of tensor categories. More recently, tensor categories and these generalizations of classical algebraic notions have also been used to study boundary conformal field theories and Dbranes in string theory.
This course is an introduction to the theory of tensor categories and its applications in representation theories, quantum groups, knot invariants and conformal field theories. I will start with a review of basic notions in the theory of categories. The theories and applications of monoidal categories, tensor categories, symmetry tensor categories, braided tensor categories and modular tensor categories will be discussed next. Then I plan to discuss examples of modular tensor categories constructed from representations of quantum groups and vertex operator algebras.
Prerequisites: I will assume that the students have
some basic knowledge in algebra, as covered in
the firstyear graduate courses.
This course was originally numbered 555:01 (Sel. Topics in Algebra). It was
renumbered 560 because the registrar cannot get good programmers.

640:569 Selected Topics in Logic S. Thomas HLL 525 TTh 6; 4:305:50
This is an introductory course on proving independence results in set
theory. The only prerequisites are some basic set theory, including
cardinals, ordinals and transfinite induction. Initially we shall
follow the lazy man's approach to obtaining independence results;
namely, we shall study the consequences of the following two extra
settheoretic axioms.
The Diamond Axiom \Diamond: a combinatorial principle which
says intuitively that there exists a fortuneteller who correctly
predicts the future often enough to be useful.
Martin's Axiom (MA +  CH): a
powerful strengthening of the negation of the Continuum Hypothesis.
We shall see that there are many independent statements
S such that ZFC + MA +  CH implies S, while
ZFC + \Diamond implies S. For example, this is true of
the following statement.
The Souslin Hypothesis: Suppose that the linear order
{ X, < } is complete and dense without endpoints.
If there does not exist an uncountable family of
pairwise disjoint nonempty open intervals of X,
then { X, < } ~ \langle { R, < }.
However, there are many statements S whose independence cannot be
established using \Diamond and MA + CH. For example, while
the following statement is independent of ZFC, it is implied by
both ZFC + \Diamond and ZFC + MA +  CH.
Additivity of Measure: If \kappa < 2^{\aleph_{0}} and
A_{\alpha} \subseteq R is a nullset for each
\alpha < \kappa, then \bigcup_{\alpha < \kappa}A_{\alpha}
is also a nullset.
In order to prove the independence of such statements, we shall need to learn settheoretic forcing. But at this point in the course, those students who have successfully mastered the use of Martin's Axiom will realise that they already know how to force.

The key ingredient in the statistical mechanical explanation of the emergence of macroscopic behavior from microscopic dynamics is the great disparity between the microscopic and macroscopic temporal and spatial scales. This gives rise to autonomous macro behavior in accord with the "law of large numbers". One can also go beyond that to obtain fluctuations and large deviations. This is beautifully captured, for equilibrium systems, by the elegant formalism of Gibbsian ensembles. There is no such general formalism for nonequilibrium systems and the subject is still in a state of exciting development.
This course will treat the subject from both the mathematical and physical point of view. Topics will include:

1. Microscopic and macroscopic descriptions of systems containing
many elementary units.
2. Gibbs ensembles, free energy and correlation functions.
3. High temperature and low density expansions.
4. Phase transitions, low temperature behavior.
5. Nonequilibrium phenomena.
6. Applications of statistical mechanical ideas and methods to biological, sociological and economic systems.
A surprisingly large amount of the theory can be discussed in terms of idealized models; Ising spin systems, lattice gases, hard sphere fluids, etc. which require only little knowledge of physics or chemistry.
Prerequisite: A general mathematical background equivalent to that of a second year graduate student in math or a knowledge of stat. mech. obtained from a physics, chemistry or engineering course in the subject.
Time period will be determined by students' schedule. If you have questions please see me in room 612 of Hill Center; phone 53117; email: lebowitz@math.

There is no textbook that covers all the material of the course and in the past we've had no text for the course. A number of books will be placed on reserve at the library. This year I'm considering using the following text (I'm awaiting receipt of a copy of the book from the publisher.)
The grade in the course is based on problem sets. There will be 5 to 7 problem sets, which will normally be assigned every other week. There are no exams.
Prerequisites: For Mathematics Ph.D. students: no formal prerequisites. For graduate students from other departments and undergraduates: permission of instructor. At various points in the course, we will need a variety of standard undergraduate material: linear algebra (350), advanced calculus (411), complex analysis (403) and elementary probability theory (477).

Mathematical finance is an emerging discipline wherein mathematical tools are used to model financial markets and solve problems in finance. Finance as a subfield of economics concerns itself with the valuation of assets and financial instruments as well as the allocation of resources. History and experience have produced fundamental theories about the way economies function and the way we value assets. Mathematics comes into play because it allows theoreticians to model the relationship between variables and represent randomness in a manner that can lead to useful analysis. Mathematics, then, becomes a tool chest from which researchers can draw to solve problems, provide insights and make the intractable model tractable.
Our course will primarily consist of an introduction to some of the most important mathematical tools in use today by practitioners of mathematical finance, stochastic partial differential equations, which is used to price options, derivatives, and other complex financial securities, and extreme value theory, used in risk analysis. After an introduction, as needed, to the background theory of probability and stochastic processes, we shall focus on diffusion processes, such as a Brownian motion, and jump diffusion processes. In discussing applications, such as the BlackScholes option pricing formula, we shall give an introduction to derivative securities.
We shall also discuss the application of stochastic processes to risk analysis. Empirical observation suggests that large market movements occur more often than models based on a convenient normal probability distribution would indicate  so, in reality, probability distributions accurately modeling the behavior of the market should have ?fat tails?. Hence, we shall discuss extreme value theory and its application to risk analysis. Time permitting, techniques for measuring and managing the risk of trading and investment positions will be discussed, including the portfolio risk management technique of ValueatRisk, stress testing, and credit risk modeling. Important applications include risk analysis for credit derivatives and collateral debt obligations.
Principal Texts:Stochastic Differential Equations, Øksendal
Brownian Motion and Stochastic Calculus, Karatzas and Shreve
Derivatives, Wilmott
Our target audience is second graduate students or higher in all areas of mathematics, as well as graduate students in statistics, economics, and business, so we shall do our best to cater for a diverse audience. For all graduate students, familiarity with basic probability theory at the level of an applied text such as Papoulis is important background knowledge. Students in mathematics and statistics should ideally have an enthusiasm for learning how mathematics is used in finance, while economics and business students should have an interest in analytical, quantitative methods.
