Geometric Construction of Killing Spinors and Supersymmetry Algebras in Homogeneous Spacetimes
Abstract
We show how the Killing spinors of some maximally supersymmetric supergravity solutions whose metrics describe symmetric spacetimes (including AdS,AdS× S and Hpp-waves) can be easily constructed using purely geometrical and group-theoretical methods. The calculation of the supersymmetry algebras is extremely simple in this formalism.
