A nonexistence result for nonlinear parabolic equations with singular measures as data

Abstract

In this paper we prove a nonexistence result for nonlinear parabolic problems with zero lower order term whose model is $$ \begin{cases} u_{t}- Δ_p u+|u|^{q-1}u=λ& \text{in}\ (0,T)\timesΩ u(0,x)=0 & \text{in}\ Ω,\\ u(t,x)=0 & \text{on}\ (0,T)\times\partialΩ, \end{cases} $$ where $Δ_p ={\rm div }(|\nabla u|^{p-2}\nabla u)$ is the usual $p$-laplace operator, $λ$ is measure concentrated on a set of zero parabolic $r$-capacity ($1<p<r$), and $q$ is large enough.
