报告摘要：We are concerned with the existence and multiplicity of prescribed mass positive solutions to Schrodinger equations with general critical nonlinearity, in particular, in the pure mass supercritical case and the mass mixed critical case. Precisely, for the pure mass supercritical case, under related mild assumptions, the existence of mountain pass normalized solutions is obtained for all prescribed mass $c>0$. We also capture its precise asymptotic behavior as $c$ goes to zero as well as $c$ goes to infinity. For the mass mixed case, there exist at least two different positive normalized solutions for small $c>0$. One is a local minimizer and the other one is a mountain pass solution. We also establish a sequence of properties for the local minimizer including the uniqueness and asymptotic behavior, etc. The asymptotic behavior of the mountain pass solution as $c\rightarrow 0^$ is also studied. Our results solve a sequence of open problems proposed by Soave( J. Funct. Anal., 279(6):108610, 2020).
