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

Abstract

We propose a holographic description of mathcal{N} = 4 super Yang-Mills on the four-dimensional real projective space mathbbm{RP} 4. We first construct the dual background in the framework of five-dimensional mathcal{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.
