✦ Synopsis

We use Beck's quasi-additivity of Tsallis entropies for n independent subsystems to show that like the case of n ¼ 2, the entropic index q approaches 1 by increasing system size. Then, we will generalize that concept to correlated subsystems to find that in the case of correlated subsystems, when system size increases, q also approaches a value corresponding to the additive case.

We consider statistically independent non-identical subsystems with different entropic indices q 1 and q 2 . A relation between q 1 , q 2 and q 0 (for the entire system) extends a power-law for entropic index as a function of distance r. A few examples illustrate a role of the proposed constraint q

We revisit the issues on the thermodynamic property of stellar self-gravitating system arising from Tsallis' non-extensive entropy. Previous papers (Physica A 307 (2002) 185; ibid. 318 (2003) 387) have revealed that the extremum-state of Tsallis entropy, the so-called stellar polytrope, has consiste
