This talk follows from the paper by del Pino, Felmer and Kowalczyk in Int. Math. Res. Not. 2004, no. 30, 1511–1527. They consider the degree-one symmetric vortex solution to the Ginzburg-Landau equation in R^2. In particular, they prove that this solution is a strict minimizer of the related energy functional for variations in a natural Hilbert space derived from the quadratic form of the linearized equation. As a corollary they obtain a Fredholm alternative theorem for the linearized Ginzburg-Landau operator.
