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…
Toric 2-group anomalies via cobordism
Joe Davighi, Nakarin Lohitsiri
2-group symmetries arise in physics when a 0-form symmetry and a 1-form symmetry intertwine, forming a generalised group-like structure. Specialising to the cas…
The Chronicles of IIBordia: Dualities, Bordisms, and the Swampland
Arun Debray, Markus Dierigl, Jonathan J. Heckman +1
In this work we investigate the Swampland Cobordism Conjecture in the context of type IIB string theory geometries with non-trivial duality bundle. Quite remarkably, we find that m…
