巴拿赫空间中发展算子的指数二分性

Exponential dichotomies of evolution operators in Banach spaces

Nicolae Lupa, Mihail Megan

摘要:

本文在巴拿赫空间的不可逆发展算子的一般背景下,研究了三种二分性概念(指数二分性,一致指数二分性和强指数二分性).说明了这些概念之间的联系。利用格林函数的概念,给出了强指数二分性的必要条件和充分条件.给出了一些例子,证明了某些蕴涵型定理的逆是无效的。

英文摘要:

This paper considers three dichotomy concepts (exponential dichotomy, uniform exponential dichotomy and strong exponential dichotomy) in the general context of non-invertible evolution operators in Banach spaces. Connections between these concepts are illustrated. Using the notion of Green function, we give necessary conditions and sufficient ones for strong exponential dichotomy. Some illustrative examples are presented to prove that the converse of some implication type theorems are not valid.
