I will consider a random walk in random environment obtained by putting iid bond weights $\mu_e$ on the bonds in the lattice $Z^d$.(Here $d\ge 3$). We assume $\mu_e \ge 1$, but have heavy tails: $P(\mu_e > t) \sim t^{-\alpha}$ with $\alpha \in (0,1)$...

The term ‘anomalous diffusion’ is used in the physics literature to refer to Markov processes with the property that E|X_t-X_0|^2 grows either faster or slower than linearly. In this talk I will give a survey of results in this area, including random...
