Uniqueness of Positive Radial Solutions To Singular Critical Growth Quasilinear Elliptic Equations

In this paper, we prove that there exists at most one positive radial weak solution to the following quasilinear elliptic equation with singular critical growth $$\{\begin{array}{ll}-{\mathrm{\Delta }}_{p}u-{\displaystyle \frac{\mu }{\mathrm{\mid }x{\mathrm{\mid }}^p}\mathrm{\mid }u{\mathrm{\mid }}^{p-2}u}{\displaystyle =\frac{\mathrm{\mid }u{\mathrm{\mid }}^{\frac{(N-s)p}{N-p}-2}u}{\mathrm{\mid }x{\mathrm{\mid }}^s}}+\lambda \mathrm{\mid }u{\mathrm{\mid }}^{p-2}u& \text{in }B,\\ u=0& \text{on }\mathrm{\partial }B,\end{array}$$ where $B$ is an open finite ball in ${\mathbb{R}}^N$ centered at the origin, $1<p<N$, $-\mathrm{\infty }<\mu <((N-p)\mathrm{/}p{)}^p$, $0\le s<p$ and $\lambda \in \mathbb{R}$. A related limiting problem is also considered.
