Summary: Let $\Omega\subseteq\bbfR^N$ be a bounded open set, $N\ge 2$, and let $p> 1$; we study the asymptotic behavior with respect to the time variable $t$ of the entropy solution of nonlinear parabolic problems whose model is \align u_t(x,t)- \Delta_p u(x,t)= \mu\quad &\text{in }\Omega\times (0,T),\\ u(x,0)= u_0(x)\quad &\text{in }\Omega,\endalign where $T> 0$ is any positive constant, $u_0\in L^1(\Omega)$ a nonnegative function, and $\mu\in{\Cal M}_0(Q)$ is a nonnegative measure with bounded variation over $Q= \Omega\times(0, T)$ which does not charge the sets of zero $p$-capacity; moreover, we consider $\mu$ that does not depend on time. In particular, we prove that solutions of such problems converge to stationary solutions.
