摘要
In this article, we consider existence and nonexistence of solutions to problem {-△pu+g(x,u)|↓△|^p=f in -Ω,u=0 on Ω with 1〈p〈∞ where f is a positive measurable function which is bounded away from 0 in Ω, and the domain Ω is a smooth bounded open set in R^N(N≥2). Especially, under the condition that g(x, s) = 1/|s|^α (α〉0) is singular at s = 0, we obtain that α 〈 p is necessary and sufficient for the existence of solutions in W0^1,p(Ω) to problem (0.1) when f is sufficiently regular.
