Holography for $$ \mathcal{N} $$ = 4 on $$ \mathbbm{RP} $$4

Abstract

Abstract We propose a holographic description of $$ \mathcal{N} $$ N = 4 super Yang-Mills on the four-dimensional real projective space $$ \mathbbm{RP} $$ RP 4. We first construct the dual background in the framework of five-dimensional $$ \mathcal{N} $$ N = 8 gauged supergravity, and then uplift it to a new one-half BPS solution of type IIB supergravity. A salient feature of our solution is the presence of a bulk naked singularity whose local behavior resembles that of an O1− plane in flat space.
