Resumen:
An analysis of the thermodynamic behavior of quantum systems can be performed from a geometrical perspective investigating the structure of the state space. We have developed such an analysis for nonextensive thermostatistical frameworks, making use of the q-divergence derived from Tsallis entropy. Generalized expressions for operator variance and covariance are considered, in terms of which the fundamental tensor is given.
