I will introduce new 2d gravity/matrix model dualities. I will present two such examples: a spacelike Liouville theory coupled to a timelike Liouville theory; and coupling two Liouville theories with complex central charges. I will explain that the former model is related to a dilaton gravity theory with negative cosmological constant, while the latter is a model admitting solutions with both a positive and negative cosmological constant, thereby providing a controllable holographic duality involving deSitter. Based on work (in progress) in collaboration with Scott Collier, Lorenz Eberhardt, and Victor Rodriguez.
