Higher Orbital Integrals on Motion Groups and Mackey Deformation
Angel Román, Yanli Song, Xiang Tang
We 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 integra…

Heat kernel, large-time behavior, and representation theory
Shu Shen, Yanli Song, Xiang Tang
Given a real reductive group , the purpose of this paper is to show an asymptotic formula of the large-time behavior of the -trace of the heat operator on the associated symm…

Lefschetz formula for locally symmetric spaces
Yanli Song
Let be a semi-simple real Lie group of real rank one and be a discrete subgroup in such that has finite volume. We introduce a new group -algebra $…
