title: Chaos in the centers of galaxies.
abstract: We compare diverging evolution of a two-component (gas+stars) galactic disk embedded in a "live" halo with that of an identical pure stellar disk. Our modeling supports the conjecture that the growth of central concentration in galaxies dissolves the main family of regular orbits in the stellar bar and assists in the formation of a galactic bulge.
