We extend a recent result of McKenzie, and show that it is an un-decidable problem to determine if 4 appears in the typeset of a finitely generated, locally finite variety.

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-...
