Abstract

Let Ω\Omega be a bounded domain in RN{\mathbb R}^N and T>0T>0. We study the problem \begin{equation} (P)\left\{ \begin{array}{lll} u_t - \Delta u \pm g(u) &= \mu \quad &\text{in } Q_T:=\Omega \times (0,T) \\ \phantom{------,} u&=0 &\text{on } \partial \Omega \times (0,T)\\ \phantom{----,} u(.,0) &=\omega &\text{in } \Omega. \end{array} \right. \end{equation} where μ\mu and ω\omega are bounded Radon measures in QTQ_T and Ω\Omega respectively and g(u)eauqg(u) \sim e^{a |u|^q} with a>0a>0 and q1q \geq 1. We provide a sufficient condition in terms of fractional maximal potentials of μ\mu and ω\omega for solving (P).
