Lie n-algebras of BPS charges
Hisham Sati, Urs Schreiber
We uncover higher algebraic structures on Noether currents and BPS charges. It is known that equivalence classes of conserved currents form a Lie algebra. We show that at least for…

The WZW term of the M5-brane and differential cohomotopy
Domenico Fiorenza, Hisham Sati, Urs Schreiber
We combine rational homotopy theory and higher Lie theory to describe the WZW term in the M5-brane sigma model. We observe that this term admits a natural interpretation as a twist…

String structures associated to indefinite Lie groups
Hisham Sati, Hyung-bo Shim
String structures have played an important role in algebraic topology, via elliptic genera and elliptic cohomology, in differential geometry, via the study of higher geometric stru…
