Supergravity and the large N limit of theories with sixteen supercharges
Abstract
We consider field theories with sixteen supersymmetries, which include U(N) YangMills theories in various dimensions, and argue that their large N limit is related to certain supergravity solutions. We study this by considering a system of Dbranes in string theory and then taking a limit where the brane world volume theory decouples from gravity. At the same time we study the corresponding Dbrane supergravity solution and argue that we can trust it in certain regions where the curvature (and the effective string coupling, where appropriate) are small. The supergravity solutions typically have several weakly coupled regions and interpolate between different limits of string M theory.
