The objectives of the work presented in this proposal are to describe the dynamical interaction between the star and gas dynamical component surrounding single and binary black holes in galaxy cores by using of realistic Nbody models. We aim to study the evolution in times of relaxation, covering ’collisional’ nuclei (with short relaxation times) as well as ’collisionles’ nuclei (relaxation times as long as the age of the universe). This will allow us to understand the past, present and possible future evolution of galactic nuclei harbouring SMBHs. NBody techniques will be used to evolve models in non-spherical (triaxial) geometries. The influence of stellar evolution and collisions will be studied.
