内容简介

本书研究的内容为非经典扩散方程在时间依赖空间中的吸引子，受到时间依赖整体吸引子的一些研究成果的启发，我们首先研究了时间依赖整体吸引子和强吸引子的存在性，之后通过调整对时间依赖函数的假设，如重新设置其下界和单调性，得到了一些在时间依赖空间中关于拉回吸引子的存在性和正则性、以及拉回吸引子和整体吸引子的上半连续性的成果，它们都是新的尝试，并且通过这些模型的研究为在时间依赖空间中研究吸引子提供了一些新的思路和方法。此外，注意到时间依赖空间的范数中包含了时间依赖函数，因此很容易知道在此类空间中研究吸引子的存在性或其吸引子的其他性质要比在Sobolev空间中更为复杂和困难，例如在证明吸收集和渐近紧性时计算量会大大增加等。虽然计算和分析较为困难，但相空间范数中时间相关项的存在拓宽了以往的研究框架，使人们能够在更接近物理现实的模型中对解的长时间行为进行讨论，促进了对动力系统解的适定性的研究进程，具有重要意义。
