Abstract
A homogeneous gas of atoms with hyperfine spin F = 1 is considered below th e critical temperature of the Bose-Einstein condensation. The general struc ture of the correlation functions (both for density and spin fluctuations) and their connection to the thermal Green's functions are worked out. The d amping of the modes is calculated in the random-phase approximation.
