Petitta, Francesco
A non-existence result for nonlinear parabolic equations with singular measures as data.
(English)
[J] Proc. R. Soc. Edinb., Sect. A, Math. 139, No. 2, 381-392 (2009). ISSN 0308-2105; ISSN 1473-7124/e

Summary: We prove a non-existence result for nonlinear parabolic problems with zero lower-order terms whose model is \align u_t-\Delta_pu+|u|^{q-1}u &=\lambda \quad\text{in }(0,T)\times\Omega,\\ u(0,x)&=0\quad\text{in }\Omega,\\ u(t,x)&= 0\quad\text{on }(0,T)\times\partial\Omega, \endalign where $\Delta_p= \text{div} (|\nabla u|^{p-2}\nabla u)$ is the usual $p$-Laplace operator, $\lambda$ is measure concentrated on a set of zero parabolic $r$-capacity $(1<p<r)$ and $q$ is large enough.
