The maximization of Tsallis entropy with complete deformed functions and the problem of constraints

Abstract

We first observe that the (co)domains of the q-deformed functions are some subsets of the (co)domains of their ordinary counterparts, thereby deeming the deformed functions to be incomplete. In order to obtain a complete definition of $q$-generalized functions, we calculate the dual mapping function, which is found equal to the otherwise \textit{ad hoc} duality relation between the ordinary and escort stationary distributions. Motivated by this fact, we show that the maximization of the Tsallis entropy with the complete $q$-logarithm and $q$-exponential implies the use of the ordinary probability distributions instead of escort distributions. Moreover, we demonstrate that even the escort stationary distributions can be obtained through the use of the ordinary averaging procedure if the argument of the $q$-exponential lies in (-$\infty$, 0].
