Abstract
We consider field theories with sixteen supersymmetries, which include U(N) Yang-Mills theories in various dimensions, and argue that their large N limit is related to certain supergravity solutions. We study t his by considering a system of D-branes in string theory and then taki ng a limit where the brane world volume theory decouples from gravity. At the same time we study the corresponding D-brane supergravity solu tion and argue that we can trust it in certain regions where the curva ture (and the effective string coupling, where appropriate) are small. The supergravity solutions typically have several weakly coupled regi ons and interpolate between different limits of string M theory.
