**Fall 2009**

**Meetings:** TR 9:30-10:45, Van Vleck B131

**Instructor:** Benedek Valkó

**Office:** 409 Van Vleck

**Phone:** 263-2782

**Email:** valko at math dot wisc dot edu

**Office hours:** Tuesday 13:30-14:30 or by appointment

I will use the class email list to send out
corrections, announcements, please check your wisc.edu email
from time to time.

**Evaluation:** Students taking the course for credit are
expected to write up two or three lectures in consultation with
the instructor. There will also be (non mandatory) homework
exercises.

**Course description:**

The course is an introduction to random matrix theory. We will
cover results on the asymptotic properties of various random
matrix models (Wigner matrices, Gaussian ensembles, Dyson's
beta-ensemble). We will investigate the limit of the empirical
spectral measure both on a global and local scale.

**Prerequisites:** Basics in probability theory and linear
algebra. Some knowledge of stochastic processes will also be
helpful.
