Dynamical behavior of nonclassical diffusion equation with perturbed parameter and memory

In this paper, we mainly investigate the existence and regularity of uniform attractor for non-autonomous nonclassical diffusion equation with perturbed parameter and hereditary memory under more general assumptions on memory kernel $ k $. In addition, the upper semicontinuity of this family of attractors with respect to perturbation parameters $ \nu $ is also proved. In particular, the nonlinearity $ f $ satisfies the polynomial growth of arbitrary order.
