Weak upper semicontinuity of pullback attractors for nonautonomous reaction-diffusion equations

Convergence of nonautonomous multivalued problems with large diffusion to ordinary differential inclusions

“…In the last years some authors have considered this problem for parabolic equations generated by a p-laplacian operator with variable exponent (see [34,40,23,36]), which appear in models of electrorheological fluids and image processing (see e.g. [20,25] and the references therein).…”
