In this work we study direct star collisions and star-disk interactions occurring in the central region of active galactic nuclei (AGN) (between the Schwarzschild radius and the black hole gravitational influence radius) to understand the AGN mass supply and the stellar system kinematics near the AGN disk. Relative velocities of stars within this region are high enough (close to the escape velocity from surface of a star) to cause a full star disruption at their collisions. In our given AGN model the interactions of supermassive black hole (SMBH), compact stellar cluster (CSC) and accretion disk (AD) governs the dynamical evolution of the system as a whole. We use a direct N-body integration (based on the Hermite scheme) to demonstrate the role of the collisional process of single stars in the region.
