چکیده
Solutions in multidimensional gravity with m p-branes related to Toda-like systems (of general type) are obtained. These solutions are defined on a product of n + 1 Ricci-flat spaces M 0 × M 1 ×. .. × M n and are governed by one harmonic function on M 0. The solutions are defined up to the solutions of Laplace and Toda-type equations and correspond to null-geodesics of the (sigma-model) target-space metric. Special solutions relating to A m Toda chains (e.g. with m = 1, 2) are considered.

A subclass of recently discovered class of solutions in multidimensional gravity with intersecting p-branes related to Lie algebras and governed by a set of harmonic functions is considered. This subclass in case of three Euclidean p-branes (one electric and two magnetic) contains a cosmological solution to D = 11 supergravity related to hyperbolic Kac-Moody algebra F 3 (of rank 3).

Black hole generalized p-brane solutions for a wide class of intersection rules are obtained. The solutions are defined on a manifold that contains a product of n − 1 Ricci-flat " internal " spaces. They are defined up to a set of functions H s obeying a non-linear differential equations (equivalent to Toda-type equations) with certain boundary conditions. A conjecture on polynomial structure o...
