✦ Synopsis

Fluctuations of the number of particles for the dilute
interacting gas with Bose-Einstein condensate are considered. It
is shown that in the Bogolubov theory these fluctuations are
normal. The fluctuations of condensed as well as noncondensed
particles are also normal both in canonical and grand canonical
ensembles.

The notion of fluctuation indices, characterizing thermodynamic stability of statistical systems, is advanced. These indices are especially useful for investigating the stability of nonuniform and trapped atomic assemblies. The fluctuation indices are calculated for several systems with Bose-Einstei

## Abstract The quantum plasma of Bose and Fermi particles is considered. A scheme of equation linearization for density matrix with the exchange interaction taken in account is proposed and the equation solution is found. An expression for Hartree‐ Fock dielectric permeatability with the exchange
