University of Toronto PDE/Applied Math/Analysis Seminar Friday March 31, 3:10-4pm 6183 Bahen Center SPEAKER: Ivana Alexandrova TITLE: The Scattering Amplitude at a Maximum of the Potential ABSTRACT: We consider the semi-classical scattering amplitude for short range potential perturbations of the Laplacian at an energy which is a non-degenerate maximum of the potential. We prove an asymptotic expansion in the semi-classical parameter of the scattering amplitude at such energies. ------------------------------------------------------------------ University of Toronto PDE/Applied Math/Analysis Seminar http://www.math.toronto.edu/appmath/ 2005-2006 organizers: Pieter Blue pblue@ math.toronto.edu Almut Burchard almut@ math.toronto.edu Bob Jerrard rjerrard@ math.toronto.edu ------------------------------------------------------------------
