Study finds modular classes help in proving Berezin volumes for supersymmetric theories.
We define a new type of manifold and show it has properties like a pseudo-Riemannian manifold.
We prove that, for M theory or type II, generic Minkowski flux backgrounds preserving supersymmetries in dimensions correspond precisely to integrable generalised structures, where is the generalised structure group defined by the Killing spinors. In other word…
