Three-block p-branes in various dimensions Original Research Article

It is shown that a Lagrangian, describing the interaction of the gravitation field with the dilaton and the antisymmetric tensor in arbitrary dimensional space-time, admits an isotropic p-brane solution consisting of three blocks. Relations with known p-brane solutions are discussed. In particular, in ten-dimensional space-time the three-block p-brane solution is reduced to the known solution, which recently has been used in the D-brane derivation of the black hole entropy.
