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-* x M-1 x (. . .) x M-n, where R-* is a time manifold, M-1 is an Einstein manifold and M-i (i > 1) are Ricci-flat manifolds. Certain examples of S-brane solutions related to A(1) + (. . .) + A(1), 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.
