... then the U(N) Yang-Mills theory gives a non-perturbative definition o f string theory on AdS. And, by taking the limit N → ∞, we can extract the (ten dimensional string theory) flat space physics, ... 2.2, we summarize the geometry of AdS spaces and gauged supergravities. In chapter 3, we “derive” the correspondence between supersymmetric Yang Mills theory and string theory...
