Killing spinors on supersymmetric P-branes

Abstract

A class of p-brane solutions for supersymmetric gravity theories with negative cosmological constant are proposed and analyzed. The solutions are purely bosonic and contain a worldsheet and a transverse section. The classification relays on the number of intrinsic Killing spinors on the worldsheet and the transverse section. A explicit discussion of the classification is performed for the four dimensional worldsheet case.
