Abstract
In this paper, schwar zschild metric and boltzmann equation have been used to calculate the number density of stars in a galaxy, and general relativity has been used to obtain the projected number densities. The results show that the projected density obtained under the above consideration concentrates in a small radius, which means the center of the galaxy with a massive black hole at its center is very bright while the outside is very dim.
