Speaker: Jean-Louis Tu, University of Metz

Abstract: Twisted K-theory is the natural framework to understand Thom isomorphism for vector bundles which are not K-oriented and Poincaré duality. We start by reviewing basic definitions and properties of twisted K-theory. Then, we explain a construction of wrong-way functoriality in K-theory. Finally, we will see how non-integral indices of elliptic operators can be interpreted in this context.
