Expression of Some Special Functions through <i>q</i>-Exponentials of the Nonadditive Statistical Mechanics

Abstract

Generalized q -exponentials functions are employed to make a generalization of complete and incomplete gamma functions. We obtain a generalization of this class of special functions which are very important in the fields of probability, statistics, statistical physics as well as combinatorics and we derive some of its properties. One gets that the generalized gamma function obtained whether approaches of the standard gamma function for a specific q values such as q = q 0 &asymp; 0.9 value suffering a large variation with the variation of q .
