Generalized uncertainty principle and correction value to the black hole entropy
Recently, there has been much attention devoted to resolving the quantum
corrections to the Bekenstein-Hawking entropy of the black hole. In particular,
many researchers have expressed a vested interest in the coefficient of the
logarithmic term of the black hole entropy correction term. In this paper, we
calculate the correction value of the black hole entropy by utilizing the
generalized uncertainty principle and obtain the correction term caused by the
generalized uncertainty principle. Because in our calculation we think that the
Bekenstein-Hawking area theorem is still valid after considering the
generalized uncertainty principle, we derive that the coefficient of the
logarithmic term of the black hole entropy correction term is negative. This
result is different from the known result at present. Our method is valid not
only for single horizon spacetime but also for double horizons spacetime. In
the whole process, the physics idea is clear and calculation is simple. It
offers a new way for studying the condition that Bekenstein-Hawking area
theorem is valid
