报告摘要:We are concerned with the existence, multiplicity of prescribed mass positive solutions to Schrodinger equations with general nonlinearity and Sobolev critical growth. The pure mass supercritical case and the mass mixed critical case are both considered. In the pure mass supercritical case, under related mild assumptions, we establish the existence of mountain pass normalized solutions for all prescribed mass. The asymptotic behavior is also investigated when the mass is small or large. In the mass mixed case, two positive normalized solutions are obtained for small mass. One is a local minimizer and the other one is a mountain pass solution. The asymptotic behavior of mountain pass solutions is considered when the mass is small.
