TRIPLE M-BRANE SOLUTIONS AND SUPERSYMMETRY

Golubtsova A. A., Ivashchuk V. D.

Information About Author:

We study composite M-brane solutions in 11-dimensional supergravity. The supersymmetric solutions describing orthogonally intersecting M-branes are dened on the product of Ricci-at manifoldsMi. The amount of preserved supersymmetries depends upon certain numbers of (chiral) parallel spinors on factor spaces Mi and brane sign factors. Three examples of triple M-brane con urations are considered and the numbers of unbroken SUSY are obtained.

Keywords: M-branes, parallel spinors, supergravity, supersymmetry
