Query: Cosmological singularities, AdS/CFT and de Sitter deformations   We review aspects of certain time-dependent deformations of $AdS/CFT$
containing cosmological singularities and their gauge theory duals. Towards
understanding these solutions better, we explore similar singular deformations
of de Sitter space and argue that these solutions are constrained, possibly
corresponding to specific initial conditions.
