    am adding references (here) on 3-twisted de Rham cohomology generalized to equivariance/orbifolds

    • CommentTimeAug 19th 2021

    started some lines on the definition of equivariant twisted de Rham cohomology according to Tu&Xu and others (here).

    It’s telegraphic for the moment, since first I wrote out some technical preliminaries (here) which made me run out of steam here.

    More later.

    I have added (here) some more lead-in words for the equivariant case (but still thin) and then I started to spell out (here) detail/proof for the claims implicit in FHT 07, (3.5).

    (What I don’t see yet is how to prove that the action of π 1\pi_1 on the cohomology of the fiber is trivial, so that their Serre spectral sequence really applies – have left a comment on this here.)

    Thanks. I have added publication data (here) and cross-linked with Atiyah&Segal05.
