Correspondence between supersymmetric Yang–Mills and supergravity theories

Abstract

AdS/CFT-correspondence establishes a relationship between supersymmetric gravity (SUGRA) on Anti-de-Sitter (AdS) space and supersymmetric Yang-Mills (SYM) theory which is conformaly invariant (CFT).The AdS space is the solution of the Einstein-Hilbert equations with a constant negative curvature.Why is this relationship important?What kind of relationship is this?How does one find it?The purpose of this text is to answer these questions.We try to present the main ideas and arguments underlying this relationship, starting with a brief sketch of old string theory statements and proceeding with the definition of D-branes and a description of their main features.We finish with the observation of the correspondence in question and the arguments that favor it.
