Hawking temperature as the total Gauss–Bonnet invariant of the region outside a black hole
Abstract We provide two novel ways to compute the surface gravity ( $$\kappa $$ κ ) and the Hawking temperature $$(T_{H})$$ ( T H ) of a stationary black hole: in the first method $$T_{H}$$ T H is given as the three-volume integral of the Gauss–Bonnet invariant (or the Kretschmann scalar for Ricci-f...
