基于维数论的SRB和平衡测度

SRB and equilibrium measures via dimension theory

Vaughn Climenhaga

摘要:

众所周知,一致双曲流的SRB和平衡测度在稳定叶和不稳定叶上的测度中具有乘积结构,其标度性质由势函数给出.我们描述了一个建设这些叶措施类似的定义Hausdorff措施,依靠Pesin Pitskel的描述拓扑压力作为一个维度特征,使用Bowen球。这些叶测度是由作者Ya为离散时间系统构造的。Pesin和A.泽勒洛维奇在这里的连续时间设置中,标度性质的描述更完整,我们使用类似的过程与双面Bowen球直接产生平衡测度本身。

英文摘要:

It is well-known that SRB and equilibrium measures for uniformly hyperbolic flows admit a product structure in terms of measures on stable and unstable leaves with scaling properties given by the potential function. We describe a construction of these leaf measures analogous to the definition of Hausdorff measure, relying on the Pesin-Pitskel' description of topological pressure as a dimensional characteristic using Bowen balls. These leaf measures were constructed for discrete-time systems by the author, Ya. Pesin, and A. Zelerowicz. In the continuous-time setting here, the description of the scaling properties is more complete, and we use a similar procedure with two-sided Bowen balls to directly produce the equilibrium measure itself.
