摘要:

应用时标和时标上指数二分性的定义研究线性系统指数二分性在变时标下的粗糙度问题, 给出了扰动系统在不同时标上稳定流形和不稳定流形的关系.

关键词: 时标, 指数二分性, 不变流形

Abstract:

We mainly applied the conceptions of time scales and exponential dichotomy on time scales to study the roughness for exponential dichotomy on different time scales and discussed the relationship between stable/unstable manifolds for the perturbed equation on different time scales.

Key words: time scales, exponential dichotomy, invariant manifolds
