Calculation of Entropy of the Sphere Symmeric Static Black Hole
Li-Qin Mi · 2005
With the density of entropy of curved space-time,we have calculated black hole entropy directly,and avoided the difficulty of solving the field equation.Because the density of entropy is divergent on the event horizon,the cutoff factor was used to prevent divergences.The result we calculated is that the black hole entropy is proportional to the horizon area.
