The radius of the horizon is given by 1/(2M), where M is the mass of the black hole. The topology of the central singularity is that of a corner. The radiation emitted very far from the black hole is thermal with temperature M/(2π). The back-reaction problem is solved to one-loop order.12 pages, Revtex, 2 figuresHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
