Some group cohomology calculations in stable homotopy theory
ESB 4133 (PIMS Lounge)
Fri 3 Jun 2016, 11:00am-12:00pm

Abstract

 The cohomology of certain p-adic Lie groups plays a central role in chromatic homotopy theory. In this talk I will discuss these groups and discuss some of their elementary group theoretical structure.  Then I will explain some recent group cohomology calculations relevant for stable homotopy theory. In particular I will highlight the result of some highly non-trivial calculation resulting in a surprising isomorphism which cries out for a conceptual explanation.

Stability of heat kernel estimates and parabolic Harnack inequalities for jump processes on metric measure spaces
ESB 2012
Thu 23 Jun 2016, 3:00pm-4:00pm

Abstract

We consider mixed-type jump processes on metric measure spaces and prove the stability of two-sided heat kernel estimates, heat kernel upper bounds, and parabolic  Harnack inequalities. We establish their stable equivalent characterizations in terms of the jump kernels, modifications of cut-off Sobolev inequalities, and the Poincar\'e inequalities. In particular, we prove the stability of heat kernel estimates for \alpha -stable-like processes even with \alpha\ge 2, which has been one of the major open problems in this area. We will also explain applications to stochastic processes on fractals.
 
This is a joint work with Z.Q. Chen (Seattle) and J. Wang (Fuzhou).
