Abstract: This talk is concerned with the Schrodinger-Poisson-Slater (SPS) equation with double critical exponents. Such exponents appear in the Coulomb-Sobolev inequality, and one is the Sobolev exponent and the other is called the Coulomb exponent here. We study the existence of nontrivial solutions of the SPS equation. This can be done by solving a variational problem with lack of compactness which is caused by those two critical exponents. Although the concentration compactness principle can be used to deal with the lack of compactness caused by the Sobolev exponent, it seems difficult to handle the other lack of compactness caused by the Coulomb exponent. In addition, we discuss the equivalent conditions for ground states obtained to the SPS equation.
