Finite-dimensional global and exponential attractors for the reaction–diffusion problem with an obstacle potential

Finite-dimensional global and exponential attractors for the reaction–diffusion problem with an obstacle potential

A reaction-diffusion problem with an obstacle potential is considered in a bounded domain of $\R^N$. Under the assumption that the obstacle $\K$ is a closed convex and bounded subset of $\mathbb{R}^n$ with smooth boundary or it is a closed $n$-dimensional simplex, we prove that the long-time behavior of the solution …
