In this paper we deal with a p-laplacian equation ut-Δpu=∫Ωuqdx-aur with null Dirichlet boundary conditions in a bounded domain Ω(∩)RN,where p>2,q, r≥1, a>0. We establish local theory of the solution and obtain that under certain conditions of q, r, Ω, a the solution of equations exists globally or blows up in finite time.
