Composite S-brane solutions related to Toda-type systems

Composite S-brane solutions in multidimensional gravity with scalar fields and fields of forms related to Toda-like systems are presented. These solutions are defined on a product manifold R** M1 * ??? * Mn, where R*is a time manifold, M1 is an Einstein manifold and Mi (i > 1) are Ricci-flat manifolds. Certain examples of S-brane solutions related to A1 + ??? + A1, Am Toda chains and those with ʹblock-orthogonalʹ intersections (e.g. SM-brane solutions) are singled out. A Kasner-like asymptotical behaviour of the solutions is shown when certain restrictions are imposed.
