Abstract
The Holstein-Primakoff boson mapping st finite temperature and in the frame work of the thermo field dynamics (TFD) is applied to treat a fermion-boson Hamiltonian. The interaction between pairs of fermions and bosons is const ructed in a model which allows for a condensate, The evolution of the conde nsate as a function of the temperature is investigated. [S0556-2813(99)0670 5-1].
