More M-branes on product of Ricci-flat manifolds
Abstract
Partially supersymmetric intersecting (non-marginal) composite M-brane solutions defined on the product of Ricci-flat manifolds M0 x M1 x ... x Mn in D= 11 supergravity are considered and formulae for fractional numbers of unbroken supersymmetries are derived for the following configurations of branes: M2 - M2, M2 - M5, M5 - M5 and M2 - M2 - M2. Certain examples of partially supersymmetric configurations are presented.
