ON GAUGE-GRAVITY CORRESPONDENCE AND OPEN-CLOSED STRING DUALITY

In this paper we discuss some aspects of gauge-gravity correspondence as part of open-closed string duality. In such a correspondence people find a super-gravity dual of a super-symmetric gauge theory. Some physically interesting theories such as SUSY Yang-Mills admit such a SUGRA dual. It then gives very useful information on the side of gauge theory, even in the regime of strong coupling.
