Some rigidity results for supergravity backgrounds in 11 dimensions
Emanuele Di Bella, Willem A. de Graaf, Andrea Santi
This paper is a contribution to the supersymmetry gap problem for supergravity backgrounds in dimensions. We study restrictions on the curvature of and, us…

Fermionic Spencer Cohomologies of D=11 Supergravity
C. A. Cremonini, P. A. Grassi, R. Noris +2
We combine the theory of Cartan-Tanaka prolongations with the Molien-Weyl integral formula and Hilbert-Poincaré series to compute the Spencer cohomology groups of the Poinca…
