Stability of Motion of ,-Body Systems,is leads us to revisit some of the old results concerning geodesic stability on Lagrangian manifolds. These cannot be applied directly but may be useful when properly reinterpreted. A method for doing that is described along with some tests of its validity and possible future applications.

On the Possibility of 2D Dynamical Chaos in Astrophysical Disks,uations. Derived necessary and sufficient conditions of 2-D description are fulfilled rather seldom in astrophysical disks. Under this conditions we derived the 2-D equation with scalar and vector nonlinearities describing the dynamics of gaseous disk rotating in solid-body manner. From our study it

The Observed Turbulent Spectrum of Cloudy Population of the Milky Way as an Evidence of a Weak Ross For small-scale perturbations the equation can be reduced to the well known nonlinear equation for Rossby waves — Charney-Obukhov equation. The spectrum of weak turbulence obtained from this equation leads to the observed by Mayers and Solomon et al. relations between the fundamental parameters of

Spectra of Stretching Numbers and Helicity Angles in Dynamical Systems,We study such spectra in conservative and dissipative mappings of 2 degrees of freedom and in conservative mappings of 3-degrees of freedom. In 2-D conservative systems we found that the lines of constant stretching number have a fractal form.
