Products and push-forwards in parametrised cohomology theories
arXiv:math/0611225
Abstract
We define a symmetric monoidal structure on the parametrised stable homotopy category over a base space with an action of an operad. We discuss products, orientations and push-forwards in parametrised cohomology theories corresponding to parametrised ring spectra. Finally, we construct parametrised ring spectra representing twisted K-theory and twisted Spinc-cobordism.
