Biased random walks in random environments
Biased random walks in random environments

Nina Gantert, TU Munich
We present several questions (and some answers) about biased random walks on percolation clusters and biased random walks among random conductances. In particular,听听we address ballisticity, monotonicity of the speed as a function of the strength听of the bias and the Einstein relation.
The talk is based on joint works with Noam Berger, Xiaoqin Guo, Matthias Meiners, Sebastian M眉ller and Jan Nagel.
