Differential cohomology (encyclopedia article)
Arun Debray
We give an overview of differential cohomology from the point of view of algebraic topology. This includes a survey of several different definitions of differential cohomology grou…
Adams spectral sequences for non-vector-bundle Thom spectra
Arun Debray, Matthew Yu
When is one of the spectra , , , , , or , there is a standard approach to computi…
Bordism for the 2-group symmetries of the heterotic and CHL strings
Arun Debray
In the presence of a nonzero B-field, the symmetries of the heterotic string form a 2-group, or a categorified group, as do the symmetries of the CH…
Constructing the Virasoro groups using differential cohomology
Arun Debray, Yu Leon Liu, Christoph Weis
The Virasoro groups are a family of central extensions of , the group of orientation-preserving diffeomorphisms of , by the circle group . We…
Differential Cohomology: Categories, Characteristic Classes, and Connections
Araminta Amabel, Arun Debray, Peter J. Haine
We give an overview of differential cohomology from a modern, homotopy-theoretic perspective in terms of sheaves on manifolds. Although modern techniques are used, we base our disc…
