The Ginzburg-Landau equations are a model for superconductivity, in which the crucial singularities are topological singularities of vortex type. We will describe some results obtained with Etienne Sandier on the dynamics of vortices in Ginzburg-Landau, which are obtained by a Gamma-convergence-based method of convergence which gives criteria to prove that solutions to the gradient-flow of energies which Gamma-converge to the solutions of the gradient-flow of the limiting energy. We will also describe some results on vortex-collisions.
