We apply the perturbative technique which was previously
developed in cosmology to now describe
the gravitational field of a galaxy with arbitrary
rotation curve. We use a Schwarzschild background as
starting point, however with the correct physical
coordinates. In the perturbation theory we find two
classes of metric perturbations, (i) stationary
perturbations in a 3‐dimensional
vicinity of the central
black hole and (ii) non‐stationary
perturbations in an infinitely thin disk. Since the metric perturbations
directly give the matter density the theory so explains
the structure of disk galaxies with a bulge.
