摘要:

In this article, we consider existence and nonexistence of solutions to problem

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 RN(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 W01,p(Ω) to problem (0.1) when f is sufficiently regular.

关键词: quasilinear elliptic equations, existence and nonexistence, gradient terms, singular weights
