Brownian motion reading group

The aim of this course is to carry on the study of Brownian motion after the Graduate course "Brownian motion" in Semester 1, 2011/2012. The material we cover includes Hausdorff dimension, potential theory of Brownian motion, intersections and self-intersections of Brownian paths and exceptional sets for Brownian motion.

We follow Peter Mörters and Yuval Peres' book "Brownian motion", which is a readable and formally self-contained account of the theory. The book can be downloaded from Peter Mörters' website

The group is organised by Maren Eckhoff. Everybody is welcome to attend.

Schedule

The course takes place on Wednesdays 09.15-11.05 in the Wolfson lecture theatre 4W 1.7 unless stated otherwise. If you would like to present one of the lectures, please contact the organiser.
