Ek. Lenzi et al., Remarks on (1-q) expansion and factorization approximation in the Tsallis nonextensive statistical mechanics, PHYS LETT A, 289(1-2), 2001, pp. 44-50
The validity of (1 - q) expansion and factorization approximations are anal
yzed in the framework of Tsallis statistics. We employ exact expressions fo
r classical independent systems (harmonic oscillators) by considering the u
nnormalized and normalized constraints. We show that these approximations c
annot be accurate in the analysis of systems with many degrees of freedom.
