Abstract
We develop the BPS (Bogomol’nyi-Prasad-Sommerfield) preon conjecture to analyze the supersymmetric solutions of supergravity. By relating the notions of Killing spinors and BPS preons, we develop a moving G-frame method or to analyze their associated generalized holonomies. As a first application we derive here the equations determining the generalized holonomies of supersymmetric solutions and, in particular, those solving the necessary conditions for the existence of BPS preonic solutions of the standard supergravity. We also show that there exist elementary preonic solutions, i.e., solutions preserving 31 out of 32 supersymmetries in a Chern-Simons type supergravity. We present as well a family of worldvolume actions describing the motion of pointlike and extended BPS preons in the background of a D’Auria-Fré type -related supergravity model. We discuss the possible implications for M theory.
