Abstract
The cyclic activity of AGN may either be caused by the changes of fuel supply to the central engine, or by the processes intrinsic to the accretion disk. Here we consider the latter possibility, assuming that the mean accretion rate is constant, and the periodic changes of the disk luminosity appear due to the instability cycle operating in its inner parts, with possible transition to advective flow (ADAF).
