摘要：

研究了R^kPDMATHABMOR ^{N-k}中的-Delta_p型拟线性退化奇异椭圆方程u = \frac{u^{p^*(s)-1}}{|y|^t} $ in a smooth bounded domain Ωin R^n=R^k \times R^{N-k}$，x=（y，z），2 \leq k<N且\geq 3，1<p<2，0 \leq s \leq p，0 \leq t \leq s，p^*（s）= \frac{p(n-s)}{n-p} .研究了t<s时解的存在性，t=s和s<k时在星形区域上解的不存在性（\frac{p-1}{p}）.当t<\frac{p-1}{p}（\frac{p-1}{p}）时，当0< \al <1时，解在C^{1，\al }（Ω）中.当t<k（\frac{p-1}{p}）时，解的正则性可改进为W^{2，p}（Ω）类.利用对称性方法研究了柱对称区域上奇异集的一些性质。

英文摘要：

We study quasilinear degenerate singular elliptic equation of type -Delta_p u = \frac{u^{p^*(s)-1}}{|y|^t}$ in a smooth bounded domain Ωin R^n=R^k \times R^{N-k}$, x=(y,z) in R^k \times R^{N-k}, 2 \leq k<N and N \geq 3, 1<p<2, 0\leq s\leq p, 0\leq t\leq s, p^*(s)=\frac{p(n-s)}{n-p}. We study existence of solution for t<s, non-existence in a star-shaped domain for t=s and s<k(\frac{p-1}{p}). We also show that solution is in C^{1,\al}(Ω) for some 0<\al<1 provided t<\frac{k}{N}(\frac{p-1}{p}). The regularity of solution can be improved to the class W^{2,p}(Ω) when t<k(\frac{p-1}{p}). We also study some properties of the singular sets in a cylindrically symmetric domain using the method of symmetry.
