Abstract
It was discovered in recent months that the anti-de Sitter (AdS) backgrounds involved in all familiar top-down examples of AdS/CFT duality follow from applying a transverse nonrelativistic brane limit to string/M theory on (asymptotically) flat spacetime. In this note we show that an exactly analogous statement holds for de Sitter (dS) backgrounds relevant to particular instances of dS/CFT duality, which are obtained via a longitudinal Carrollian brane limit. This statement makes direct contact with the holographic duality inferred by Hull via temporal T-duality.
