Abstract
Collective oscillations in quasi-one-dimensional superconductors caused by fluctuations of the order parameter phases of different bands have been investigated. The case of the electron-phonon mechanism of superconductivity in systems with small densities of carriers and the case of the non-phonon mechanism of superconductivity have been considered. The possibility for the appearance of two exciton-like modes as well as collective excitations with the quadratic dispersion law has been shown. Collective oscillations have been clarified in three-band superconductors. The Bogolubov-Anderson acoustic mode is also obtained.
