The Novikov conjecture and group extensions
March 6, 2020 1pm, 646 PGH
Abstract
The Novikov conjecture is an important problem in higher dimensional topology. It claims that the higher signatures of a compact smooth manifold are invariant under orientation preserving homotopy equivalences. The Novikov conjecture is a consequence of the strong Novikov conjecture in the computation of the K-theory of group C*-algebras. In this talk, I will talk about the Novikov conjecture for groups which are extensions of coarsely embeddable groups. In particular, I will talk about the computation of the K-theory of some C*-algebras.
