一个K理论Selberg迹公式

A K-theoretic Selberg trace formula

Bram Mesland, Mehmet Haluk Sengun, Hang Wang

摘要:

设G是半单李群,H是G中的一致格.塞尔伯格迹公式是一个等式,它是通过用两种不同的方法计算希尔伯特空间L^2(G/H)上与检验函数相关的卷积算子的迹而得到的。本文给出了G和H的极大群C ~*-代数的迹公式的上同调解释。作为应用,我们利用的作用,群C*-代数作为收件人的椭圆型微分算子的高指数,我们得到的Selberg迹公式的Barbasch和Moscovici从我们的指数理论版本。

英文摘要:

Let G be a semisimple Lie group and H a uniform lattice in G. The Selberg trace formula is an equality arising from computing in two different ways the traces of convolution operators on the Hilbert space L^2(G/H) associated to test functions. In this paper we present a cohomological interpretation of the trace formula involving the K-theory of the maximal group C*-algebras of G and H. As an application, we exploit the role of group C*-algebras as recipients of higher indices of elliptic differential operators and we obtain the index theoretic version of the Selberg trace formula developed by Barbasch and Moscovici from ours.
