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

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