Extended regions of accretion disks around supermassive black holes in bright AGNs are prone to gravitational instability, star formation and stellar dynamical evolution with feedback to the disks' structure. Spectroscopic data provide vital clues on the stellar and residual black hole populations. Their dynamical interaction with each other, their natal disks, and other massive companions in active and dormant galactic nuclei is remarkably analogous to that in the context of planet formation, evolution, and solar system dynamics. These processes contribute to the observed brightness andspectral-energy distribution of AGN disks and the kinematic properties of the nuclear cluster in the Galactic Center. They also lead to the prolific production and coalescence of black holes as candidates for some gravitational wave events.
