Aim. The dynamics of Bose-condensed atoms in a three-well symmetric chain trap is studied. Methodology. The temporal evolution of the population of atoms in the wells is investigated theoretically. Results. It is shown that under conditions of exact resonance, there are oscillatory regimes of evolution of atoms in the wells of a three-well trap, as well as the rest of the system. Research implications. The dynamics of tunneled Bose-condensed atoms in a three-well trap is determined by the initial number of atoms in the wells and the initial phase.
