Course content

Topics in Complex analysis deals with the theory of analytic functions of several complex variables. In particular the differences between the theory of one and of several variables will be emphasised: While for every domain D in C there exist holomorphic  functions f on D that do not extend analytically outside D, there are many domains G in C^n so that every holomorphic function extends to a larger domain G. Understanding this phenomenon is a major goal of the course. There is a close relation with solvability of the inhomogeneous Cauchy-Riemann equations, which we will also discuss. These are always solvable in one variable, but in the several variable case solvability depends on the domain. Another major difference is that biholomorphic mappings are much more difficult to understand. We will see that there is no Riemann mapping theorem and that there are very many biholomorphic maps from C^n to (subsets of) C^n

Objectives

At the end of the course, the student can solve problems involving Reinhardt domains, domains of holomorphy, and pseudoconvexity. She can identify and construct plurisubharmonic functions with prescribed properties, is able to solve relevant inhomogeneous Cauchy-Riemann equations, either by L^2 or by kernel methods.  the student is able to read some of the literature in several complex variables. The students will be able to read as a group parts of Rosay and Rudin "Holomorphic maps from C^n to C^n". The successful student will be able to write a masters thesis in complex analysis or complex dynamics.
