摘要: 当非线性项满足次临界增长条件时, 在时间依赖空间中讨论带时间依赖记忆核的非局部非经典扩散方程解的长时间动力学行为. 先利用Galerkin逼近法得到解的适定性和正则性, 然后借助分解技巧和积分估计法证明时间依赖全局吸引子的存在性和正则性.

关键词: 非局部非经典扩散方程, 时间依赖记忆核, 时间依赖全局吸引子, 正则性

Abstract: When the nonlinear term satisfied the subcritical growth condition, long-time dynamical behavior of solutions for nonlocal nonclassical diffusion equation with time-dependent memory kernels was discussed. We first used  Galerkin approximation method to obtain the well-posedness and regularity of the solution, and then used decomposition technique and integral estimation method to prove the existence and regularity of the time-dependent global attractors.

Key words: nonlocal , nonclassical diffusion equation,  , time-dependent memory kernel, time-dependent global attractor, regularity
