Anderson Model
Parabolic Anderson model in a dynamic random environment: random conductances
... Random walks with random conductances have been studied intensively in the literature. For a recent overview, we refer the reader to Biskup [2]. The goal of the present paper is to study the version of the Parabolic ...
