Standing wave and travelling wave solutions for a fourth order Schrödinger equation
Speaker: Jean-Baptiste Casteras (CMAFcIO, Universidade de Lisboa).
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 and renormalized solutions. We will then be interested in their qualitative properties, in particular their stability.
