Generalized Uncertainty Principle And Black Hole Entropy

Since Hawking had proposed the concept of black hole entropy, physicists have devoted themselves to studythe essence of black hole and the origin of black hole entropy. Researchers developed the Generalized Uncertainty Principle on the basis of Heisenberg Uncertainty Principle which is used to calculate the entropy of black holes. In this paper we use the Generalized Uncertainty Principle to calculate the entropy of Barriola-Vilenkin black hole and Vaidya de-sitter black hole with double horizons, we also introduced the Extended Generalized Uncertainty Principle and Modified Uncertainty Principle on the basis of Generalized Uncertainty Principle which are used to calculate the entropy correction of several kinds of black holes.The first chapter we introduce the evolution of stars、the basicconcepts of black hole and laws of thermodynamics of black hole.The second chapterwe introduce the Generalized Uncertainty Principle and black hole entropy, and we use the Generalized Uncertainty Principle to calculate the entropy of Barriola-Vilenkin black hole and Vaidya de-sitter black hole with double horizons. In the third chapterwe extended the Generalized Uncertainty Principle and introduce the Extended Generalized Uncertainty Principle and the Modified Uncertainty Principle which are used to calculate the entropy correction of Schwarzschild black Reissner-Nordstrom black hole and Garfinkle-Horowitz-Stromingerdilaton black hole.
