Generalized uncertainty principle and the quantum entropy of rotating black hole

The entropy of rotating Kerr-Newman-Kasuya black hole due to massive charged fields (bosons and fermious) is calculated by using the new eqation of state density motivated by the generalized uncertainly relation. The result show the entropy does not depend on the mass and the charge but the parameter gimel, the area A and the spin of the field. Moreover, an imporved approximation is provided to calculated the scalar entropy
