The authors propose a holographic duality between a gravitational theory on a d+1 dimensional wedge spacetime and a d-1 dimensional conformal field theory (CFT), which lives on the corner of the wedge. This is a generalization of the usual AdS/CFT duality. For certain particular cases, the authors check the duality by computing the free energy, entanglement entropy and correlation functions of the dual CFTs from gravity.
