Abstract: I will review the geometric construction of pure supergravity Lagrangians in four dimensions in the presence of a non-trivial spacetime boundary, focusing in particular on the N = 2 AdS4 theory on a manifold with boundary. The latter recently turned out to be related, in the spirit of the holographic correspondence, to a D = 3 super-Chern Simons theory featuring “unconventional local supersymmetry”, relevant for the description of graphene-like systems for specific spatial geometries.
