*“**Standing wave solutions for a nonlinear Schrödinger equation with mixed
dispersion**”*



*Abstract:*

In this talk, we will be interested in standing wave solutions to a fourth
order nonlinear Schrödinger equation having second and fourth order
dispersion terms. This kind of equation naturally appears in nonlinear
optics. In a first time, we will establish the existence of ground-state
solutions. We can obtain them with two different ways : either by imposing
a L^2 mass constraint or via a L^p constraint. We will then be interested
in their qualitative properties : positivity, symmetry, exponential decay,
uniqueness and orbital stability. We will conclude with some open
questions. Joint work with Denis Bonheure, Ederson Moreira Dos Santos and
Robson Nascimento.





Tutti gli interessati sono invitati a partecipare.
