非均匀环境下的鲍文方程

Bowen's equation in the non-uniform setting

Vaughn Climenhaga

摘要:

我们表明,鲍文方程,它的特点豪斯多夫维数的某些集的拓扑压力的一个扩大的共形映射,适用于更大的一般性比迄今为止已经建立。特别地,我们考虑一个紧致度量空间的任意子集Z,并且只要求Z上的下李雅普诺夫指数是正的,以及一个缓和的收缩条件。除此之外,这使我们能够计算具有抛物周期点的映射的李雅普诺夫指数的维数谱,并将符号空间的任意子集的豪斯多夫维数与拓扑熵联系起来。

英文摘要:

We show that Bowen's equation, which characterises the Hausdorff dimension of certain sets in terms of the topological pressure of an expanding conformal map, applies in greater generality than has been heretofore established. In particular, we consider an arbitrary subset Z of a compact metric space and require only that the lower Lyapunov exponents be positive on Z, together with a tempered contraction condition. Among other things, this allows us to compute the dimension spectrum for Lyapunov exponents for maps with parabolic periodic points, and to relate the Hausdorff dimension to the topological entropy for arbitrary subsets of symbolic space with the appropriate metric.
