Scientific paper

The factors influencing the star formation in the inner regions of Seyfert galaxies are considered. The UV and X-ray radiation of the galactic nucleus with the luminosity Lion ⪆ 1044erg/s results in the disruption of molecular clouds in the inner zone with the radius ⪆0.1 kpc during the time t = 107yr. It is shown that the outflow from the nucleus results in the transport of mass 107 - 108M_sun; into the inner zone, with the radius 0.5 - 1 kpc. Under the decrease of nuclear luminosity with time, the gas may be a mass resource for the star formation.
