关于非自治动力系统中的拉回吸引子的一个注(英文)

Notes on the pullback attractors in non-autonomous dynamics systems

首先,我们回顾了关于非紧测度的一些定义和基本性质.然后,我们给出了关于拉回吸引子存在性的两个条件之间的直接证明.

First we recall the concept of measure of noncompactness and recapitulate its basic properties. Then,we prove that the two conditions about the existence of pullback attractor are equivalent directly.
