Abstract: The method of functional integration is used to investigate the collective excitations in the superconducting state of the one-band two-dimensional Hubbard model with repulsion. The energy spectrum of the Bose modes is obtained. The existence of a branch of Bogolyubov sound is demonstrated. The phase structure and symmetry of the model are also considered.
