Title: Higher Orbital Integrals on Motion Groups and Mackey Deformation
Abstract: In this talk, I will present an explicit construction of cyclic cocycles on Cartan motion groups, which can be viewed as generalizations of orbital integrals. We show that the higher orbital integral on a real reductive group associated with a semisimple element converges to the corresponding one on the associated Cartan motion group. This is a joint work with Yanli Song and Xiang Tang.
