On the Chern character in Higher Twisted K-theory and spherical T-duality

L Macdonald, V Mathai, H Saratchandran - … in Mathematical Physics, 2021 - Springer
In this paper, we construct for higher twists that arise from cohomotopy classes, the Chern
character in higher twisted K-theory, that maps into higher twisted cohomology. We show …

Integration of singular subalgebroids by diffeological groupoids

I Androulidakis, M Zambon - arxiv preprint arxiv:2008.07976, 2020 - arxiv.org
We establish an integration theory for singular subalgebroids, by diffeological groupoids. To
do so, we single out a class of diffeological groupoids satisfying specific properties, and we …
