Description
We present the power of a geometric framework for supergravity and supersymmetric theories solely based on differential calculus on supermanifolds. The relevant field theory Lagrangians are expressed by integral forms, ready to be integrated on the full supermanifold and automatically implementing the invariance under super-diffeomorphisms. We show that different superspace formulations of a given theory arise from the same action upon suitable choices of the integral forms. We also show the analogies with algebraic structures in string field theory and several new results.
