Fluxbrane and S-brane solutions related to Lie algebras

摘要

We overview composite fluxbrane and special S-brane solutions for a wide class of intersection rules related to semi-simple Lie algebras. These solutions are defined on a product manifold R* × M_1 × ... M_1 × ... ×M_n which contains n Ricci-flat spaces M_1, ..., M_n with 1-dimensional R* and M_1. They are governed by a set of moduli functions H_s, which have polynomial structure. The powers of polynomials coincide with the components of the dual Weyl vector in the basis of simple coroots.
