Abstract
In this article, we prove a necessary and sufficient condition for symmetric Palais-Smale conditions, then apply it to assert the existence of three positive solutions of the equation $ (1.1) $ in an axially symmetric domain $D_{R}$ in which one is axially symmetric and the other two are nonaxially symmetric.
