摘要：

We show that the average absorption time tau in a certain M-urn model recently introduced by Ritort in the context of glassy dynamics has a lower bound 2(N-1) + N - 3, where N is the number of balls. A Monte Carlo scheme, which accurately estimates the absorption time even when tau similar to 10(12), indicates that for large N we have tau similar to 2(N).
