論文題目：Existence, Multiplicity of Positive Solutions for Elliptic Equations

摘　　要：

We study a class of indefinite semilinear elliptic problems and the Kirchoff type problem by using the variational methods to obtain the existence and multiplicity of positive solutions. Roughly speaking, we use the mountain pass theorem, the Palais - Smale theory and study properties of the Nehari manifold to investigate the existence and multiplicity.
