Аннотация	The processes of splitting and merging of black holes obey the composition law generated by the Tsallis– Cirto δ = 2 statistics. The same composition law expresses the full entropy of the Reissner–Nordstr¨om black hole via the entropies of its outer and inner horizons. Here we apply this composition law to the thermodynamics of the Kerr black hole. As distinct from Reissner–Nordstr¨om black hole, where the full entropy depends only on mass M and does not depend on its charge Q, the entropy of Kerr black hole is the sum of contributions from its mass M and angular momentum J, i. e. S( M, J) = S( M, 0) + 4π J( J + 1) . Here S( M, 0) is the entropy of the Schwarzschild black hole. This demonstrates that when the Kerr black hole with J 1 absorbs or emits a massless particle with spin sz = ±1/ 2, its entropy changes by | ΔS| = 2π. We also considered the quantization of entropy suggested by the toy model, in which the black hole thermodynamics is represented by the ensemble of the Planck- scale black holes – Planckons. The Tsallis–Cirto composition law is also extended to the thermodynamics of Kerr–Newman black hole and Schwarzschild–de Sitter black hole. DOI: 10. 7868/ S3034576626040122
