Normalized solutions of nonlinear Schrödinger equations and systems

The talk will be concerned with the existence of standing wave solutions of nonlinear Schrödinger equations and systems when the \(L^2\) norms of the solutions are prescribed. This topic has received a lot of attention in recent years but is still much less understood compared with the problem when the \(L^2\) norms are free. I will present a variational approach and a bifurcation approach, based on joint work with R. Molle, M. Rizzi, G. Verzini, and X. Zhong, W. Zou.
