Abstract

In this series of lectures I present a review of the geometric structures of supergravity in diverse dimensions mostly relevant to p-brane physics and to pinpoint the correspondence between the macroscopic and microscopic description of branes. In particular I review duality transformations, coset manifold structures and the general steps involved by the process of gauging supergravity lagrangians both with respect to compact, non compact and non semisimple groups. I focus specifically on the issue of the Domain Wall field theory correspondence and its relation with the gaugings of supergravity in p+2 dimensions. A complete review of the geometries involved by D=5, N=2 supergravity and of its most general form is given with emphasis on the problem of finding smooth supersymmetric realizations of the Randall Sundrum scenarios. I also give a general review of the algebraic machinery involved by the Solvable Lie algebra description of the scalar manifolds of supergravity and I emphasize its distinguished role in pinpointing the superstring interpretation of supergravity p brane solutions and the macroscopic/microscopic correspondence.
