The interplay between temperature and q-deformation in the phase transition properties of many-body systems is studied … in the particular framework of the collective q-deformed fermionic Lipkin model. It is shown that in phase transitions … occuring in many-fermion systems described by su(2)q-like models are strongly influenced by the q-deformation. …
