 Random walk in random environment: the operator theory approach

We examine a random walker on a graph which is itself random. When is the distribution of its position approximately gaussian?  Following on the work of Kipnis and Varadhan who brought spectral theory into this problem, we  show an unexpected connection to the spectral theory of unbounded operators.

All terms will be explain in the talk. This is joint work with Balint Toth.
