Abstract

We present the general dielectric formalism for Bose-Einstein condensed systems in an external potential at finite temperatures. On the basis of a model arising within this framework as a first approximation in an intermediate-temperature region for the large condensate we calculate the damping of low-energy excitations in the collisionless regime.
