Selected writings

On generalizing string topology to target spaces which need not be compact and moreover may be Lie groupoids/differentiable stacks:

• Kai Behrend, Gregory Ginot, Behrang Noohi, Ping Xu: String topology for stacks, Astérisque 343 (2012) [arxiv/0712.3857, numdam:AST_2012__343__R1_0]

On transgression in group cohomology generalized to Real $\mathbb{Z}/2$-equivariant cohomology (as appropriate for twists of KR-theory):
