Where Planar Simple Random Walk Loses its Rotational Symmetry

Date: 
Wednesday 17th June 2015 - 15:30 to 16:30
Venue: 
INI Seminar Room 1
Abstract: 
Local central limit theorems for random walks come in several shapes and forms. Lawler's books contain a number of versions which are very precise at and somewhat beyond the typical range for random walk. In this talk, I will give a detailed description of what happens for a large range of atypical points for simple random walk and will show where and how the walk loses its approximate rotational symmetry.
