Black holes, Angular momentumAbstract
The present paper reviews the change in mass of spinning black holes w.r.t. the angular momentum in AGN as proposed by Mahto, D. & Kumari, A. to show that the change in mass of spinning black holes due to change in the angular momentum decreases with increasing their masses for both categories of spin a*=1/2 & a*=1 in the same manner provided that the change in mass of spinning black holes w.r.t. the angular momentum for a*=1/2 is lesser than to that of spinning black holes of the same mass for a*=1.
