双曲群上随机游动熵的微分

Differentiating the entropy of random walks on hyperbolic groups

P. Mathieu

摘要:

我们证明了非初等双曲群上的随机游动的渐近熵是可微的,并且我们确定了它的导数为相关函数。我们也证明了类似的结果的逃逸率。

英文摘要:

We show that the asymptotic entropy of a random walk on a nonelementary hyperbolic group, with symmetric and bounded increments, is differentiable and we identify its derivative as a correlation. We also prove similar results for the rate of escape.
