Products of Thermodynamic Parameters for the Generalized Charged Rotating Black Hole and the Reissner-Nordstrom Black Hole with Global Monopole

摘要

We investigate the thermodynamics of Kerr-Newman-Kasuya black hole and theReissner-Nordstrom black hole with a global monopole on inner and outerhorizons. Products of surface gravities, surface temperatures, Komar energies,electromagnetic potentials, angular velocities, areas, entropies, horizon radiiand the irreducible masses at the Cauchy and the event horizons are calculated.It is observed that the product of surface gravities, surface temperatureproduct and product of Komar energies, electromagnetic potentials and angularvelocities at horizons are not universal quantities for these black holes.Products of areas and entropies at horizons are independent of masses of blackholes. Heat capacity is calculated for the generalized charged rotating blackhole and phase transition is observed, under certain conditions on r. ?E
