## A Liouville theorem of degenerate elliptic equation and its application

 1 School of Mathematical Science, Fudan University, Shanghai, 200433, China

Received  November 2012 Revised  February 2013 Published  April 2013

In this paper, we apply the moving plane method to the following degenerate elliptic equation arising from isometric embedding,\begin{equation*} yu_{yy}+au_y+\Delta_x u+u^\alpha=0\text{ in } \mathbb R^{n+1}_+,n\geq 1. \end{equation*} We get a Liouville theorem for subcritical case and classify the solutions for critical case. As an application, we derive the a priori bounds for positive solutions of some semi-linear degenerate elliptic equations.
