本文研究了一般形式的无穷维动力系统.利用非紧性测度理论,当非紧性测度指数衰减时,获得了紧的指数吸引集的存在性条件.同时给出了易于验证非紧性测度指数衰减的方法.
In this article,a general dynamical system is considered.By using the measure of non-compactness theory,the existence of compact exponential attracting set is obtained when the measure of non-compactness exponentially decays.Also a method is given for proving the measure of non-compactness decays exponentially.
