Thom isomorphism and push-forward map in twisted K-theory

Thom isomorphism and push-forward map in twisted K-theory

Abstract We establish the Thom isomorphism in twisted K-theory for any real vector bundle and develop the push-forward map in twisted K-theory for any differentiable map f : X → Y (not necessarily K-oriented). We also obtain the wrong way functoriality property for the push-forward map in twisted K-theory. For …
