Abstract

The 4D-5D connection allows us to view the near-horizon geometry as part of a 4D Black Hole or a 5D Black Hole. The discrepancy between the entropy/index in the two cases is resolved by introducing hair modes that live outside the horizon. After a review, we discuss the construction and analysis of modes in AdS_3 ×S^3, which connect to hair modes in the full Black Hole spacetime. We compare and contrast these near-horizon modes with analogous "hair" modes in other approaches.
