摘要：

We describe compaction and segregation in granular media in terms of microscopic lattice gas models in which the effects of geometric frustration play a crucial role. Then, exploiting the strong connections which appear with glass forming systems, we introduce a simplified master equation, based on the theory of cooperative rearrangements, to describe the above dynamic processes.
