对于一个单调扭曲映射,在一定的非退化条件下,证明了在两个相邻的具有相同旋转数的周期极小轨道之间存在无穷多个同宿轨道和异宿轨道,这表明该映射具有混沌动力学性质.我们的结果也适用于二维环面上光滑黎曼度量的测地线。
For a monotone twist map, under certain non-degenerate condition, we showed the existence of infinitely many homoclinic and heteroclinic orbits between two periodic neighboring minimal orbits with the same rotation number, which indicates chaotic dynamics. Our results also apply to geodesics of smooth Riemannian metrics on the two-dimension torus.
