摘要: 利用n维Conley-Moser条件证明了一类离散扰动非线性Schrdinger方程(NLS)的Smale马蹄的存在性．由以上结果，我们得到离散扰动NLS方程组存在不变集Λ，其动力系统与四符号变换拓扑共轭．

Abstract: The existence of Smale horseshoes for a certain discretized perturbed nonlinear Schroedinger (NLS) equations was established by using n-dimensional versions of the Conley-Moser conditions.As a result,the discretized perturbed NLS system is shown to possess an invariant set Lambda on which the dynamics is topologically conjugate to a shift on four symbols.
