摘要：

Local symmetries of a non-expanding horizon have been investigated in the 1st order formulation of gravity. When applied to a spherically symmetric horizons, only a U(1) subgroup of the Lorentz group survives as residual local symmetry that one can make use of in constructing an effective theory on the horizon.
