In a previous paper we developed an axiomatic approach to quantum mechanics
that allowed us to derived the Schrodinger equation from first principles,
using the concept of the Boltzmann-Gibbs entropy. In the present continuat
ion paper we will generalize our derivation to the whole class of Tsallis e
ntropies, whose particular case q = 1 is just the Boltzmann-Gibbs one. We w
ill thus arrive at a g-generalized Schrodinger equation presenting a great
number of new features, absent from the usual q = 1 particular case. (C) 19
