Abstract

We discuss the nonlinear generalized Rayleigh quotients method [1] as a new tool, which can be deployed in studying the orbital stability of ground states of the nonlinear Schro ̈dinger (NLS) equations. We introduce a variational functional, in which the global minimizer corresponds to the so-called fundamental frequency solutions [2] with prescribed action value. We exhibit the method on the examples of studying of the orbital stability of ground states for the non-linear Schr ̈odinger equation with a harmonic potential
