Local limit theorem for Kempermann's oscillating random walkBC1 2.01.10 (8101.02.110) (Parkring 11, 85748 Garching-Hochbrück)
The model of oscillating random walks introduced by Kempermann is one of the simplest example of a Markov chain with discontinuous statistics. We consider the situation when this chain converges, after proper rescaling, towards a skew Brownian motion. In the talk I will discuss the corresponding local limit theorem.
