GEDA (Grupo de ecuaciones diferenciales y aplicaciones) is a research team made up of people of three different universities headquartered in the Mathematics department of the Carlos III University.

The research will focus on a series of lines originated from the mathematical models of nonlinear diffusion, especially of degenerate, singular type or with geometrical origin, as well as nonlocal diffusion and the associated stationary states. Our main interests are qualitative theory (existence, uniqueness, multiplicity, regularity), the study of free boundaries, the formation of singularities in finite time and the asymptotic behaviour. Existence of positive bound and ground state solutions of systems with linearly and nonlinearly coupled nonlinear Schrödinger (NLS) and  NLS-KdV equations. Also we are interested in stability properties of some dispersive systems.
