Description
Spinor bilinears have played an important role in classification of supergravity vacuum solutions. In this talk I will present a novel reformulation of supersymmetry conditions for type II theories in terms of spinor bilinears without assuming any factorization of space-time. These bispinors can be used to define brane calibrations, namely differential forms whose integrals measure minimal energies, and I will show how supersymmetry can be rephrased in terms of calibration conditions.
I will continue by presenting an application of these techniques to the classification of Mink$_4 \times S^2$ solution in type II and M-theory, which is a preliminary step to find new compact solutions which overcame Maldacena-Nunez no-go theorem. In the end I will discuss how the bispinors reformulation can be used in the classification of non supersymmetric solutions.
