Title: Some notes on higher rho invariant

Abstract: In this talk I would like to introduce the higher rho invariant as an obstruction class. I will then focus on its applications in topology and show how to define additive higher rho map from the structure group of a topological manifold to the K theory of a certain obstruction C*-algebra. At last I hope to talk about the product formula for higher rho invariants.
