摘要

本文研究了一类具有时滞的二维非局部扩散晶格系统的长期动力学行为。首先给出了无限维时滞自治动力系统指数吸引子构造的几个充分条件。然后,利用新的解尾估计方法,克服了非局部扩散算子和多维性所带来的困难,建立了二维非局部扩散延迟格系统的指数吸引子的存在性。

Exponential attractors for two-dimensional nonlocal diffusion lattice systems with delay
In this paper, we study the long term dynamical behavior of a two-dimensional nonlocal diffusion lattice system with delay. First some sufficient conditions for the construction of an exponential attractor are presented for infinite dimensional autonomous dynamical systems with delay. Then, the existence of exponential attractors for the two-dimensional nonlocal diffusion delay lattice system is established by using the new method of tail-estimates of solutions and overcoming the difficulties caused by the nonlocal diffusion operator and the multi-dimensionality.
