On the generalized entropy pseudoadditivity for complex systems

Abstract

We show that Abe's general pseudoadditivity for entropy prescribed by thermal\nequilibrium in nonextensive systems holds not only for entropy, but also for\nenergy. The application of this general pseudoadditivity to Tsallis entropy\ntells us that the factorization of the probability of a composite system into\nproduct of the probabilities of the subsystems is just a consequence of the\nexistence of thermal equilibrium and not due to the independence of the\nsubsystems.\n
