VARIABLE STARS, THE GALACTIC HALO AND GALAXY FORMATION C. Sterken, N. Samus and L. Szabados (Eds.) 2010 Formation Mechanisms for Spheroidal Stellar Systems O. K. Sil'chenko 1 Sternberg Astronomical Institute of the Moscow State University, Moscow, Russia Abstract. Spheroidal stellar systems on various scales include elliptical galaxies, dwarf spheroidal galaxies, and globular stellar clusters. ... The formation mechanisms of the oldest globular clusters represent a puzzle yet. ... 2009). ...
... Keywords. conservative system, stability b oundary, singularity, multiple eigenvalue, p erturbation. ... Because of continuous dependence of eigenvalues on parameters a boundary of the stability domain is determined by the zero eigenvalue, while all other eigenvalues are positive. ... Using the results of Arnold [1] and a perturbation technique for eigenvalues [3, 9], a classification of singularities of stability boundaries in the generic case is obtained. ...

... In this case, the main vortex in the Benard cell is decomposed into smaller ones as a result of ten perioddoubling bifurcations. It is shown that the resulting turbulence is coherent and determinate; the fractal character (local selfsimilarity) of its spectrum is found. ... It is shown that the real atmospheric turbulence is the result of mixing of different coherent structures. ... COHERENT STRUCTURE IN A CLOSED ROOM The scheme of measurements in the LSVT spectrograph pavilion is shown in Fig. ...
