Logarithmic interaction energy for infinitely many points in the plane
Speaker: Etienne Sandier, UniversitÃ© Paris 12, Paris, France
Abstract: I will define an energy describing the interaction of infinitely many positive charges in the plane with a uniform negative background (a system sometimes referred to as a jellium by physicists). I will give some of the basic properties of this energy proved with S. Serfaty some years ago, and describe recent results obtained with Y.Ge which give a partial answer to the question of which configurations of points have finite energy. I will also if time permits describe links and applications to the theory of log-gases and weighted Fekete sets.
