Title: Higher rho invariant and pairings with higher cyclic cocyles

Abstract: In this talk, I will introduce a pairing map between K-theory of obstruction algebra and higher cyclic cocyles for the group algebras of hyperbolic groups. The main focus of this pairing is to establish a connection between two different approaches to the index theory of manifolds with boundaries. This is joint work with Xiaoman Chen, Zhizhang Xie and Guoliang Yu.
