A Study of Mathematical Model on Entropy Change of Bosonic Field of Black Holes of Spin Parameters a* = +2 & -2 in XRBs and AGN

Abstract

A Mathematical model for the change in entropy of Bosonic fields of black holes w.r.t. the mass as discussed by Mahto et al (2020) is studied for spin parameters a* =+2 & -2 in XRBs and AGN categories of black holes with calculations of their values for different masses provides the concept of the naked singularity as well as dark matter and dark energy and concludes also that this field of black holes of co-rotation decreases the entropy and counter rotation increases the entropy.
