Biased Random Walk on Dynamical Percolation

Time：Thur., 16:00-17:00 , March 7

Venue：C548, Shuangqing Complex Building A 清华大学双清综合楼A座C548

Speaker：Dominik Schmid (University of Bonn)

Abstract:

We consider a biased random walk on dynamical percolation and discuss the existence and the properties of the linear speed as a function of the bias. In particular, we establish a simple criterion to decide whether the speed is increasing or decreasing for large bias. This talk is based on joint work with Sebastian Andres, Nina Gantert, and Perla Sousi.

Quantitative equidistribution of linear random walk on the torus
AbstractConsider the action of GL_d(Z) on the d-dimensional torus R^d/Z^d. Given a probability measure on GL_d(Z) and a point on the torus, a random walk is defined. In this talk, I will report some recent progress about the equidistribution of such random walks. More precisely, I will talk about quantitative results under the assumption that the acting group has semisimple Zariski closure. Thi...
