Abstract
To study collective excitations in hot finite Fermi systems (atomic nu clei, metallic clusters), a method accounting for the influence of tem perature and the collective excitation parameters of the system on the mean field is developed using the formalism of thermofield dynamics. The role of the Pauli principle is considered more correctly than in t he standard thermal random-phase approximation.
