Enumeration of walks by winding angle
A talk in the Oberseminar Probability Theory and Mathematical Statistics series by
Andrew Elvey Price from Université Tours
| Abstract: |
How much does a random walk wind around a given point? At the large scale this question has been well understood since the 80’s thanks to work by Spitzer, Belisle, Rudnick, Hu and many others. The first exact results for this problem were given by Budd in 2017, who solved it on the square lattice. In this talk I will describe my exact solutions for a more general class of models, namely walks with small steps.
