M. within 0.1 pc of the dynamic center. This central dark mass cannot be a cluster of neutron stars. It is either a compact cluster of stellar black holes or, most likely, a single massive black hole.

Orbits in barred galaxies,parison of our method with Laskar‘s frequency analysis method is made. In 3-D systems we define one spectrum for stretching numbers and three spectra for helicity angles. A clear distinction between Arnold diffusion and resonance overlap diffusion is made.

The pattern speed of the Galactic bulge,persion ratios in Baade‘s window. From the velocity dispersion in Baade‘s window, and an assumed distance of 8 kpc to the Galactic center we obtain a mass of 2.7×10. M. and a pattern speed of 39 km s. kpc..

The galactic center dynamics,potential serves as a source of excitation of the density wave. In the both cases, the generated spiral density wave is consistent with the observed ‘mini-spiral’ if the upper limit to the black hole mass is ?10.M..
