翻译后摘要:我们考虑一个扩展的地图上定义的平面的一个开放的区域,并研究其不变集的盒维数。在映射留下不变的“强不稳定叶理”的条件下,证明了不变集的盒维数由δF+δT给出,其中δT是它横截于的维数,δF是某个涉及拓扑压的函数的根.
Abstract:We consider an expanding map defined on an open region of the plane and study the box dimensions of its invariant sets. Under the condition that the map leaves invariant a “strong unstable foliation”, we prove that the box dimension of an invariant set is given by δF+δT, where δT is its dimension transverse to and δF is the root of a certain function involving topological pressure.
