Abstract: We give an overview of a project with Dan Freed and Jacques Distler
whose goal is a precise and general formulation of orientifold backgrounds of type II
string theory. A central theme is the use of twisted equivariant differential generalized
cohomology theories. The B-field twists a version of equivariant KR theory, while the
RR fields and currents are formulated in terms of a twisted equivariant differential
KR theory. One important new result is a formula for the RR charge of an orientifold
plane at the K-theory level, which lifts the standard result of Morales-Scrucca-Serone
in integral cohomology.
