FULLY DISCRETE SCHEMES FOR THE SCHRÖDINGER EQUATION: DISPERSIVE PROPERTIES

We consider fully discrete schemes for the one-dimensional linear Schrödinger equation and analyze whether the classical dispersive properties of the continuous model are presented in these approximations. In particular, Strichartz estimates and the local smoothing of the numerical solutions are analyzed. Using a backward Euler approximation of the linear semigroup we introduce a convergent scheme for the nonlinear Schrödinger equation with nonlinearities

PROPIEDADES CUALITATIVAS DE ESQUEMAS NUMÉRICOS DE APROXIMACIÓN DE ECUACIONES DE DIFUSIÓN Y DE DISPERSIÓN

This thesis analyzes various numerical schemes for the heat, Schrödinger and wave equations. Our main goal is to describe the behaviour of the solutions of the classical finite difference approximations, focusing on their qualitative properties: decay rates, dispersion, propagation, etc. Our aim is to thoroughly study the dispersion properties of the numerical schemes for the Schrödinger and wave equations, properties which are not only important
