Abstract

The correspondence between the Kerr black hole and a boundary CFT has been conjectured recently. The conjecture has been proposed first only for the half of the CFT, namely for left movers. For right movers, the correspondence has been also found out through the suitable asymptotic boundary condition. However, the boundary conditions for these two studies are exclusive to each other. The boundary condition for left movers does not allow the symmetry of right movers, and vice versa. We propose a new boundary condition which allows both left and right movers. The isometries U(1) for the left mover and the SL(2, ) for right mover are enhanced to Virasoro algebras with and without central extensions, respectively.
