University of Toronto PDE/Applied Math/Analysis Seminar Friday 30 March, 12:10-1:00pm 2195 Bahen Center SPEAKER: Ivana Alexandrova (East Carolina University) TITLE: The Spectral Function at a Maximum of the Potential ABSTRACT: We study the structure of the spectral function for semi-classical Schrodinger operators at an energy which is a non-degenerate maximum of the potential. We prove that the spectral function at this energy is a semi-classical Fourier integral operator and give an asymptotic expansion. ------------------------------------------------------------------ University of Toronto PDE/Applied Math/Analysis Seminar http://www.math.toronto.edu/appmath/ 2006-2007 organizers: Pieter Blue pblue@ math.toronto.edu Almut Burchard almut@ math.toronto.edu Robert McCann mccann@ math.toronto.edu ------------------------------------------------------------------
