Abstract
The interplay between temperature and q-deformation in the phase trans ition properties of many-body systems is studied in the particular fra mework of the collective q-deformed fermionic Lipkin model. It is show n that in phase transitions occuring in many-fermion systems described by su(2)(q)-like models are strongly influenced by the q-deformation.
