Title: An overview of Ginzburg Landau theory within the framework of the Calculus of Variations
Speaker: Raghav Venkatraman, Indiana University
Abstract: In this expository talk, we give a gentle introduction to the theory of Ginzburg Landau vortices. We will mostly be talking about the two dimensional theory, because in this context complex variables methods are quite useful. This development by Bethuel Brezis and Helein paved way to the theory of weak Jacobians which proved crucial for the problem in higher dimensions. Time permitting, we will briefly describe this and some related time dependent problems.
