摘要: 基于Lyapunov范数研究了巴拿赫空间中演化过程的非一致指数二分性,借助Datko-Pazy方法,得到了演化过程满足非一致指数二分性的若干连续与离散形式的充要条件。所得结果推广和完善了指数稳定性与指数二分性理论的部分已有结果。

Abstract: The nonuniform exponential dichotomy of evolutionary process in Banach spaces is studied based on the Lyapunov norms.Some continuous and discrete versions of necessary and sufficient conditions for nonuniform exponential dichotomy are obtained by applying Datko-Pazy methods.The obtained conclusions are generalizations of the well-known results in exponential stability and exponential dichotomy theory.
