摘要

本文研究如下拟线性退化奇异椭圆方程解的存在性 \begin{equation*} (P_\la)\left\{ \begin{split} -\text{div}(w(x)|\nabla u|^{p-2}\nabla u) &= g_{\la}(u),\;u>0\; \text{in}\; \Om, u&=0 \; \text{on}\; \partial \Om, \end{split}\right. \end{equation*} 其中 \Om\mbRn \Om \subset \mb R^n 为光滑有界域,n3n\geq 3\la>0\la>0p>1p>1ww 为 Muckenhoupt 权函数。利用变分方法,对 g\la(u)=\laf(u)uqg_{\la}(u)= \la f(u)u^{-q} 及关于 ff 的某些假设,我们证明了对每个 \la>0\la>0(P\la)(P_\la) 解的存在性。此外,当 g\la(u)=\lauq+urg_{\la}(u)= \la u^{-q}+ u^{r} 时,我们在参数 \la\la 的适当范围内建立了 (P\la)(P_\la) 至少两个解的存在性。此处我们假设 q(0,1)q\in (0,1)r(p1,ps1)r \in (p-1,p^*_s-1)
