Abstract
The effect of the fluctuation interaction of atoms forming a condensate on solitons of the Bose- Einstein condensation is considered. A short derivation of the Gross-Pitaevsky equation is given. The averaged Lagrangian of solitons of the Bose-Einstein condensation is determined. The obtained results give an opportunity to investigate the solitons dynamics under the action of various perturbations.
