Scientific paper

This is a starting point of future work on a more detailed study of early evolutionary phases of galactic nuclei. We put into port the study of the evolution of star accretion onto a supermassive gaseous object in the central region of an active galactic nucleus, which was previously addressed semi-analytically. For this purpose, we use a gaseous model of relaxing dense stellar systems, whose equations are solved numerically. The model is shortly described and some first model calculations for the specific case of black hole mass growth in time are given. Similar concepts will be applied in future work for a system in which there is a dense interstellar medium as a possible progenitor of a black hole in the galactic centre.
