A gravity dual of ultra-slow roll inflation
We study time-dependent deformations of a certain class of backgrounds in type IIB supergravity. These backgrounds are solutions of a five-dimensional consistent truncation, relevant for gauge/gravity duality, which have the form of dS4 foliations over a fifth (radial) direction. We investigate time...
