內(nèi)容介紹：In this talk, we are concerned with the nonlinear logarithmic Schrodinger equations. First, we present some results on the existence, multiplicity, and concentration for a logarithmic Schrodinger equation. Next, we explore the existence of multiple normalized solutions to the logarithmic Schrodinger equation via the minimization techniques and the Lusternik-Schnirelmann category. Finally, we introduce the existence and multiplicity of solutions for the logarithmic Schrodinger equation with a potential on lattice graphs, and provide some differences between graph problems and continuous problems. This talk is based on some work with Claudianor O. Alves and Zhentao He.
