Title: Stability of solitary waves of nonlinear Schrodinger equation Abstract: In this talk, we consider Nonlinear Schrodinger equation (NLS) which appears in many regions of mathematical physics such as Bose-Einstein condensation, plasma physics and the[...]

Title: K-theory, representation theory, and the Baum-Connes conjecture. Speaker: Rufus Willet (U. Hawai`i) Abstract: I’ll describe what K-theory is, and why it’s relevant to representations of groups via group algebras. If the group is infinite,[...]
