TY - JOUR AU - Vasconcelos, G. L. AU - Salazar, D. S. P. PY - 2012 TI - Multicanonical Distribution and the Origin of Power Laws JF - Revista Cubana de FĂ­sica; Vol 29 No 1E (2012): March COMeeting'12 KW - N2 - A multicanonical formalism is applied to the problem of statistical equilibrium in a complex system with a hierarchy of dynamical structures. At the small scales the system is in quasi-equilibrium and follows a Maxwell-Boltzmann distribution with a slowly fluctuating temperature. The probability distribution for the temperature is determined using Bayesian analysis and it is then used to average the Maxwell-Boltzmann distribution. The resulting energy distribution law is written in terms of generalized hypergeometric functions, which display power-law tails.   UR - https://revistacubanadefisica.org/index.php/rcf/article/view?path=
