摘要: 考察了底空间为ΣN×S1的疯狂动力系统的拓扑熵, 确定其范围为lg N~2lg N; 并给出当纤维映射中含有旋转映射时该系统拓扑熵的范围.

关键词: 疯狂动力系统, 拓扑熵, (n,ε)张成集, 纤维映射

Abstract: The topological entropy of a crazy dynamic system with ΣN×S1 as the basic space is investigated, and its range is pointed out: lg N~2lg N. Moreover, a more exact result is given when the rotation maps occur in the fiber maps.

Key words: crazy dynamics, topological entropy, (n,ε)-spanning sets, fiber maps
