Role of the irreducible mass in repetitive Penrose energy extraction processes in a Kerr black hole

The concept of the irreducible mass (M_{irr}) has led to the mass-energy (M) formula of a Kerr black hole (BH), in turn leading to its surface area S=16πM_{irr}^{2}. This also allowed the coeval identification of the reversible and irreversible transformations, soon followed by the concepts of extra...
