 This book is devoted to the analysis of the large time asymptotics of the solutions of the heat equation in a random timedependent potential. The authors give complete results in the discrete case of the \(d\)dimensional lattice when the potential is, at each site, a Brownian motion in time. The phenomenon of intermittency of the solutions is discussed. Readership Research mathematicians. Table of Contents  Introduction
