Название: Diffusion of Directed Polymers in a Random Environment
Авторы: Imbrie J.Z., Spencer T.
Аннотация:
We consider a system of random walks or directed polymers interacting weakly with an environment which is random in space and time. In spatial dimensions d > 2, we establish that the behavior is diffusive with probability one. The diffusion constant is not renormalized by the interaction.
