NON-EXTREMAL INTERSECTING P-BRANES IN VARIOUS DIMENSIONS

Non-extremal intersecting p-brane solutions of gravity coupled with se veral antisymmetric fields and dilatons in various space-time dimensio ns are constructed. The construction uses the same algebraic method of finding solutions as in the extremal case and modified ''no-force'' c onditions. We justify the ''deformation'' prescription. It is shown th at the nonextremal intersecting p-brane solutions satisfy the harmonic superposition rule and intersections of non-extremal p-branes are spe cified by the same characteristic equations for the incidence matrices as for the extremal p-branes. We show that S-duality holds for non-ex tremal p-brane solutions. Generalized T-duality takes place under addi tional restrictions to the parameters of the theory, which are the sam e as in the extremal case. (C) 1997 Published by Elsevier Science B.V.
