## Classification of positive solutions of semilinear elliptic equations with Hardy term

 1 Hanbat National University, Daejeon 305-719

Received  September 2012 Revised  July 2013 Published  November 2013

We study the elliptic equation $\Delta u+\mu/|x|^2+K(|x|)u^p=0$ in $\mathbb{R}^n \setminus \left \{ 0 \right \}$, where $n\geq1$ and $p>1$. In particular, when $K(|x|)=|x|^l$, a classification of radially symmetric solutions is presented in terms of $\mu$ and $l$. Moreover, we explain the separation structure for the equation, and study the stability of positive radial solutions as steady states.
