Galactic Nonlinear Dynamic Model
We develop a model for spiral galaxies based on a nonlinear realization of
the Newtonian dynamics starting from the momentum and mass conservations in the
phase space. The radial solution exhibits a rotation curve in qualitative
accordance with the observational data.Comment: 6 pages, 1 figure. Talk given in the 7th Alexander Friedmann

Relativistic dynamics of Qqq systems
The bound state of constituent quarks forming a composite baryon is
investigated in a QCD-inspired effective light-front model. The light-front
Faddeev equations are derived and solved numerically. The masses of the spin
1/2 low-lying states of the nucleon, , and
are found and compared to the experimental data. The data is
qualitatively described with a flavor independent effective interaction.Comment: 18 pages, include 6 figures, 2 eps figures, use latex, revtex. To

Ground State Masses and Biding Energies of the Nucleon, Hyperon and Heavy Baryons in a Light-Front Model
The ground state masses and binding energies of the nucleon,
, , are studied within a constituent
quark QCD-inspired light-front model. The light-front Faddeev equations for the
composite spin 1/2 baryons, are derived and solved numerically. The
experimental data for the masses are qualitatively described by a flavor
independent effective interaction.Comment: 13 pages, include 4 eps figures, use latex, revte
