Aspects of gauge-string duality in SUSY and non-SUSY systems. / Stephen Thomas Bennett

Swansea University Author: Stephen Thomas Bennett

Abstract

We study various aspects of type IIB supergravity backgrounds related to those of Klebanov-Strassler and Chamseddine-Volkov/Maldacena-Nunez, in the context of gauge-gravity duality. We first examine the structure which can be found in the family of supersymmetric solutions, and in particular the eff...
