報(bào)告內(nèi)容摘要: In this talk, we mainly focus on a mass supercritical NLS equation with a partial confinement. Firstly, we study the existence of normalized ground states and obtain an explicit bound below which a ground state indeed exists. We also treat the mass critical case. This is joint work with Ru Yan. Secondly, we show the existence of a second solution, at a mountain pass level, when the mass is not large. This is joint work with Louis Jeanjean and solves an open problem proposed by Bellazzini, Boussaid, Jeanjean and Visciglia (Comm. Math. Phys. 353, 2017, 229-251).
