## Abstract

In this talk we outline that for every $$1<p\leq 2$$ and for every continuous function $$f\colon [0,1]\times\mathbb R\to\mathbb R$$, which is Lipschitz continuous in the second variable, uniformly with respect to the first one, each bounded solution of the one-dimensional heat equation $u_{t}-\bigl(|u_{x}|^{p-2}u_{x}\bigr)_{x}+f(x,u)=0 \qquad\text{in}\quad (0,1)\times (0,+\infty)$ with homogeneous Dirichlet boundary conditions converges as $$t\to +\infty$$ to a stationary solution. The proof follows an idea of Matano which is based on a comparison principle. Thus, a key step is to prove a comparison principle on non-cylindrical open sets.
