EVOLUTION OF GALACTIC DISCS: TWO MODES OF STAR FORMATION ABSTRACT We develop the model of the evolution of surface gas density, stellar density, star formation rates and chemical composition of galactic disc taking into account the gravitational instability of rotating gaseous layer in the scales of several kpc. ... In the model we took into account the gas return from evolved stars, a radial movement of the gas in a spiral arms and accretion of the gas into the galactic disc. ...
