Vortex Singularities in Ginzburg-Landau Type Problems - Lecture 3 of 3

Professor Radu Ignat
(Institut de Mathématiques de Toulouse)
Further Information

3 x 2 hour Lectures via Zoom (see email of 10th May 2021 for details)

Aimed at: The course is addressed to postgraduate students, postdocs and other members of the Mathematical Institute. It is an introduction to concentration phenomenon around vortices in Ginzburg-Landau type problems. The aim is to present topological methods (based on Jacobian, winding number...) that allow for detection of vortices and computation of the interaction energy between them. The purpose of this course is to analyse vortex singularities appearing in Ginzburg-Landau type problems.

The lecture will be via Zoom and the link was also sent out in an email on 10th May
