| Abstract: | By using integral representations the perturbation expansion and the Bogoliubov inequality in nonextensive Tsallis statistics
are investigated in a unified way. This procedure extends the analysis performed recently by Lenzi et al. Phys. Rev. Lett. 80, 218 (1998)] to the quantum (discrete spectra) case, for q<1. An example is presented in order to illustrate the method.
