Theory of Functions of a Complex Variable I



Text: Function Theory of One Complex Variable: Third Edition (Graduate Studies in Mathematics) *by Robert E. Greene and Steven G. Krantz
Publisher: American Mathematical Society; 3rd edition (March 29, 2006)
ISBN-13: 978-0821839621

Prerequisites: Acquaintance with analytic arguments at the level of Rudin's Principles of Modern Analysis is necessary. Some knowledge of algebra and point-set topology is useful.

Description:

The beginning of the study of one complex variable is certainly one of the loveliest mathematical subjects. It's the magnificent result of several centuries of investigation into what happens when R is replaced by C in "calculus". Among the consequences were the creation of numerous areas of modern pure and applied mathematics, and the clarification of many foundational issues in analysis and geometry. Gauss, Cauchy, Weierstrass, Riemann and others found this all intensely absorbing and wonderfully rewarding. The theorems and techniques developed in modern complex analysis are of great use in all parts of mathematics.

The course will be a rigorous introduction with examples and proofs foreshadowing modern connections of complex analysis with differential and algebraic geometry and partial differential equations. Acquaintance with analytic arguments at the level of Rudin's Principles of Modern Analysis is necessary. Some knowledge of algebra and point-set topology is useful.

The course will include some appropriate review of relevant topics, but this review will not be enough to educate the uninformed student adequately. A previous "undergraduate" course in complex analysis would also be useful though not necessary.

There are many excellent books about this subject. The official text will be Function Theory of One Complex Variable, by Greene and Krantz (American Math Society, 3rd edition, 2006). The course will cover most of Chapters 1 through 5 of the text, parts of Chapters 6 and 7, and possibly other topics. The titles of these chapters follow.
1: Fundamental Concepts; 2: Complex Lines Integrals; 3: Applications of the Cauchy Integral;4: Meromorphic functions and Residues; 5: The Zeros of a Holomorphic Function; 6: Holomorphic Functions as Geometric Mappings.





Selected Topics in Analysis



Subtitle: Topological Methods in Nonlinear Analysis

Text: Recommended: Chapters 2, 4, 7 of Gilbarg-Trudinger (not the entire book) are recommended for this course. They can be photo-copied from an original copy (second edition). I will make them available to the students that do not have them. Brezis - Functional Analysis, Springer 2011, M.A.Krasnosel'skii - Topological Methods in the Theory of Nonlinear Integral Equations (International Series of Monographs in Pure and Applied Mathematics Vol. 45)

Prerequisites: Knowledge of Lebesgue integration theory and of earlier courses in Real and Functional Analysis is a prerequisite for this class.

Description: PLEASE NOTE: THIS COURSE HAS REPLACED COURSE 16:640:507. IF YOU REGISTERED FOR 16:640:507, YOU HAVE BEEN MOVED OVER TO 16:640:509.
This course should prepare students to set up the framework and learn some of the early and basic techniques in order to solve some nonlinear PDEs via topological methods.
1- The first part of the course covers Lp-spaces (convolution, dual spaces), Wm,p_ spaces, Rellich-Kondrachov embeddings. It also covers the resolution of the Dirichlet problem Δu = f ; u = 0|∂Ω via Green's function representation techniques (less general, but useful). References for this first part of the course are Gilbarg-Trudinger Chapters 2,4,7 (I have the second edition, Springer 1983).
2- The second part of the course covers Fredholm operators of index ν and 0 (self-adjoint operators) and Diagonalization of compact self-adjoint operators in separable Hilbert spaces.
There are a number of references on this very classical subject in the literature, including Brezis, Functional Analysis, Springer 2011, Riesz-Nagy, Analyse Fonctionnelle (Academie des Sciences de Hongrie) and others...
3-The third part of the course is mainly based on the old and very classical book of M.A.Krasnosels'kii's Topological Methods in the Theory of Nonlinear Integral Equations (International Series of Monographs in Pure and Applied Mathematics Vol 45; I have the copy of the library...). There are again a number of other references in the literature, including notes by L.Nirenberg at Courant, J.T Schwartz (also Courant Lecture Notes) and excellent papers by A.Ambrosetti and P.H Rabinowitz... This third part should cover:
  • Caratheodory conditions and continuous maps from Lp(Ω­) to Lq(Ω­).
  • Finite dimensional degree theory (here, we will use a differential geometry approach. One good reference, after assuming transversality and the Morse-Sard theorem, is provided in M.Hirsch's book Differential Topology, Graduate text in Maths 33, Springer 1997)
  • Leray-Schauder degree
  • Weakly continuous functionals on the unit sphere or the unit ball of a separable Hilbert space (Z2 and S1-Lusternik-Schnirelman theory)
I hope to be able to cover all the topics of this course. Whatever will be covered will be covered in detail. Knowledge of Lebesgue integration theory and of earlier courses in Real and Functional Analysis is a prerequisite for this class.
Required and recommended sources:
Chapters 2, 4, 7 of Gilbarg-Trudinger (not the entire book) are recommended for this course. They can be photo-copied from an original copy (second edition). I will make them available to the students that do not have them.
Brezis' book, cited above, is recommended, so is M.A.Krasnoselsk'ii's book cited above.





Partial Differential Equations I



Text: Partial Differential Equations: Second Edition (Graduate Studies in Mathematics), By Lawrence C. Evans, American Mathematical Society; 2nd edition (March 3, 2010), ISBN-10: 0821849743.

Prerequisites: A strong background on advanced calculus involving multivariables (esp. Green's Theorem and Divergence Theorem). We will also use some basic facts of Lp function spaces and the usual integral inequalities (mostly completeness and Holder inequalities in L2 setting). These topics are covered in the first semester graduate real variable course (640:501).

Description: This is the first half of a year-long introductory graduate course on PDE. This introductory course should be useful for students with a variety of research interests: physics and mathematical physics, applied analysis, numerical analysis, differential geometry, complex analysis, and, of course, partial differential equations. This is the way the course will be conducted. The beginning weeks of the course aim to develop enough familarity and experience to the basic phenomena, approaches, and methods in solving initial/boundary value problems in the contexts of the classical prototype linear PDEs of constant coefficients: the Laplace equation, the D'Alembert wave equation, the heat equation and the Schroedinger equation. Next we will discuss first order nonlinear PDEs (e.g. characteristics, Hamilton-Jacobi equations), some ways to represent solutions (e.g. separation of variables, similarity solutions, Fourier and Laplace transforms, Hodograph and Legendre transform, singular perturbation and homogenizations, Cauchy-Kovalevskaya theorem). Then we discuss Soblev spaces and Soblev embedding theorems, second order elliptic equations of divergence form (existence, uniquesness, regularity), second order parabolic equations (existence, maximum principles, regularity).

Prerequisites: One complex variable and the basic Hilbert space theory from real analysis

Description:

A function with $n$ complex variables $z\in {\bf C}^n$ is said to be holomorphic if it can be locally expanded as power series in $z$. An even dimensional smooth manifold is called a complex manifold if the transition functions can be chosen as holomorphic functions. Roughly speaking, a Cauchy-Riemann manifold (or simply, a CR manifold) is a manifold that can be realized as the boundary of a certain complex manifold. Several Complex Variables is the subject to study the properties and structures of holomorphic functions, complex manifolds and CR manifolds. Different from one complex variable, if $n>1$ one can never find a holomorphic function over the punctured ball that blows up at its center. This is the striking phenomenon that Hartogs discovered about 100 years ago, which opened up the first page of the subject. Then Poincar\'e, E. Cartan, Oka, etc, further explored this field and laid down its foundation. Nowadays as the subject is intensively interacting with other fields, providing important examples, methods and problems, the basic materials in Several Complex Variables have become mandatory for many investigations in pure mathematics. This class tries to serve such a purpose, by presenting the following fundamental topics from Several Complex Variables.

(a)Holomorphic functions, plurisubharmonic functions, pseudoconvex domains and the Cauchy-Riemann structure on the boundary of complex manifolds

(b) H\"ormander's $L2$-estimates for the $\bar \partial$-equation and the Levi problem \noindent

(c) Cauchy-Riemann geometry, Webster's pseudo-Hermitian Geometry and subelliptic analysis on CR manifolds

(d) Complex manifolds, holomorphic vector bundles, Kahler Geomtry.

If time permits, other topics may be covered, such as Chern classes and Grothendieck-Riemann-Roch formula, ADE singularities, toric varieties, Grassmannians, birational geometry. I will focus on the geometric intuition behind the algebraic constructions and will try to include as many examples of algebraic varieties as possible.

Selected Topics in Algebra



Subtitle: Methods in Vertex Operator Algebra Theory

Text: I. Frenkel, J. Lepowsky and A. Meurman, Vertex Operator Algebras and the Monster, Pure and Applied Mathematics, Vol. 134, Academic Press, 1988. Supplementary Texts: I. Frenkel, Y.-Z. Huang and J. Lepowsky, On Axiomatic Approaches to Vertex Operator Algebras and Modules, Memoirs AMS, Vol. 104, Number 494, 1993; C. Dong and J.

Li, Introduction to Vertex Operator Algebras and Their Representations, Progress in Math., Vol. 227, Birkhauser, Boston, 2003.

Prerequisites: Some familiarity with the basics of vertex operator algebra theory. Students without such experience and potentially interested in this course are encouraged to consult Professor Lepowsky.

Description: We will construct lattice vertex operator algebras and generalizations, and twisted modules for such structures. This will lead to the construction of the moonshine module vertex operator algebra and of the action of the Monster sporadic finite simple group. Y.-Z. Huang's complementary method for constructing the moonshine module vertex operator algebra, using tensor category structure, will also be discussed. These ideas will be related to relevant research papers and to current research problems.

Please note: The Lie Groups/Quantum Mathematics Seminar, which will meet Fridays at 12:00, will sometimes be related to the subjects of the course. Students planning to take the course should also try to arrange to attend the seminar, although the seminar will not be required for the course.





Selected Topics in Logic



Subtitle: Choice versus Determinacy: An Introduction to Classical Descriptive Set Theory

Text: No Text required

Prerequisites: A knowledge of basic set theory, including cardinals, ordinals and the axiom of choice.

Description: The Axiom of Choice (AC) implies the existence of various pathologies on the real line R such as a non-measurable set of reals, an uncountable set of reals with no perfect subset, a 2-coloring of the 2-subsets of R with no uncountable monochromatic subset, etc. In this course, we will explore the question of whether such pathologies can arise within the "definable sets" of reals; namely, the Borel sets, the analytic sets, ... , etc. While these questions cannot be fully settled using the usual ZFC axioms of set theory, we will find that they all have negative answers if we assume the Axiom of Projective Determinacy (PD): an extra set-theoretic axiom which posits the existence of winning strategies for a broad class of infinite 2-player games. The course will cover the following topics: (1) Basic Descriptive Set Theory We will study the hierarchies of the Borel sets and projective sets, and analyze the structure of the sets in each of these hierarchies. (2) Determinacy We will study infinite 2-player games played on the real line R. We shall see that the existence of winning strategies for suitably defined games implies the non-existence of set-theoretic pathologies within the projective hierarchy. (3) Applications We will study various applications to the theory of Borel equivalence relations and the theory of the Turing degrees of relative computability.
