Title: Higher eta invariants, Rationality and K-theory of C*-algebras

Abstract: In this talk, I will discuss Lott's higher eta invariants from a more K-theoretic viewpoint. We not only obtain simpler and conceptual proofs of some of the results in literature, but also give new results regarding rationality of these invariants. The talk is based on joint work with G. Yu.
