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 _* × M₁ × ··· × M_n, where _* is a time manifold, M₁ is an Einstein manifold and M_i (i > 1) are Ricci-flat manifolds. Certain examples of S-brane solutions related to A₁ + ··· + A₁, A_m Toda chains and those with 'block-orthogonal' intersections (e.g. SM-brane solutions) are singled out. A Kasner-like asymptotical behaviour of the solutions is shown when certain restrictions are imposed.
