A Proposed Absolute Entropy of Near Extremal KerrNewman Black Hole
Abstract
Some problems have been found as to the definition of entropy of black hole being applied to the extremal KerrNewman case, which has conflicts with the third law of thermodynamics. We have proposed a new modification for the near extremal one, which not only obeys the third law, but also does not conflict with other results in black hole thermodynamics. Then we proved that the inner horizon has temperature and proposed that the inner horizon contributes to the entropy of the near extremal one so that the entropy of it has a modified form and vanishes at absolute zero temperature.
