Applying incomplete statistics to nonextensive systems with different $q$ indices

Abstract

The nonextensive statistics based on the qq-entropy Sq=i=1v(pipiq)1qS_q=-\frac{\sum_{i=1}^v(p_i-p_i^q)}{1-q} has been so far applied to systems in which the qq value is uniformly distributed. For the systems containing different qq's, the applicability of the theory is still a matter of investigation. The difficulty is that the class of systems to which the theory can be applied is actually limited by the usual nonadditivity rule of entropy which is no more valid when the systems contain non uniform distribution of qq values. In this paper, within the framework of the so called incomplete information theory, we propose a more general nonadditivity rule of entropy prescribed by the zeroth law of thermodynamics. This new nonadditivity generalizes in a simple way the usual one and can be proved to lead uniquely to the qq-entropy.
