Abstract
The effect of finite thickness on the properties of disk galaxies is calculated on the basis of a rigorous mathematical treatment in terms of Green function and Bessel Fourier transformation. In our approach, the mass of the galactic halo is determined by fitting the observed rotation curve with a five-component model. We not only choose a bulge, a thin disk and a halo but also include a nuclear bulge (i.e. the Galactic Nucleus) and a thick disk. The effect of finite thickness of the disk on both the radial and vertical self-gravity is considered in detail. The vertical dynamics of this three-dimensional system is also investigated.
