Hi all, We're moving back to 3:00PM this semester. Hope to see you, Iddo. Title: Differential operators of arbitrary order between zero and two Speaker: Moritz Kassmann (Bielefeld) Time: Friday, January 24, 2014 at 3:00 pm Place: MSB 203 Abstract: We discuss a subclass of (integro-)differential operators of fractional order. These operators are related to semi-groups and stochastic processes in a natural way. In the talk we present definitions, basic results as well as recent developments for linear and nonlinear equations. The main emphasis is on new intrinsic scaling properties.
