Abstract:Schrdinger-Poisson system is obtained by coupling Schrdinger equation and Poisson equation.With a strong physical background,it is mainly used to study the motion law of micro matter in electric field.In this paper,a class of Schrdinger-Poisson system with critical exponents on bounded domains is considered and two positive solutions are obtained by Mountain Pass Theorem and Ekeland variational principle.

Keywords:Schrdinger-Poisson system;critical exponent;Mountain Pass Theorem;Ekeland variational principle;positive solutions
