Study of Mathematical Model for the Change in Entropy of AGN BHs of Spin Parameter a*=+5/2 & -5/2

Abstract

In the present work, a mathematical model for the change in entropy of fermionic fields of black holes with respect to the mass as given by  is used to study the behavior of BHs in the AGN for spin  a*=+5/2 & -5/2 and also the calculation of their values for different masses. The outcome of this work concludes that there is decrease and increase in entropy due to co - rotation and counter rotation of Fermionic field of BHs respectively.
