论文摘要

我们研究了两个圆环的同态同态的传递性与拓扑混乱之间的关系。我们表明,如果$ \ mathbb {t}^2 $的瞬时同构同态对身份是同型的,并且既有固定点,又有一个未固定的点,那么它具有拓扑马蹄。我们还表明,如果$ \ mathbb {t}^2 $的传递同源物与dehn Twist是同质的,那么它是Aperiodic的,或者具有拓扑组合。

We study the relationship between transitivity and topological chaos for homeomorphisms of the two torus. We show that if a transitive homeomorphism of $\mathbb{T}^2$ is homotopic to the identity and has both a fixed point and a periodic point which is not fixed, then it has a topological horseshoe. We also show that if a transitive homeomorphims of $\mathbb{T}^2$ is homotopic to a Dehn twist, then either it is aperiodic or it has a topological horseshoe.
