Non Abelian T-duality and Holography. / Niall Thomas Macpherson

Swansea University Author: Niall Thomas Macpherson

Abstract

"We study non-abelian T-duality as a supergravity solution technique and explore its application to holography. We consider well understood geometries which describe the strong coupling regime of minimally supersymmetric gauge theories in 3 and 4 dimensions. We then use non-abelian T-duality to...
