Worldsheet Analysis of Gauge/Gravity Dualities

Understand

Gauge/gravity dualities are investigated from the worldsheet point of view.

• In [arXiv:0706.1163] and [arXiv:0708.2463], a duality between 4d SYM and supergravity on AdS_5xS^5 has been partly explained by using an anisotropic scale invariance of worldsheet theory.
• In this paper, we refine the argument and generalize it to lower dimensional cases.
• We show the correspondence between the Wilson loops in (p+1)-d SYM and the minimal surface in the black p-brane background.
