The paper contains a brief review of an approach to quantum entanglement
based on analysis of dynamic symmetry of systems and quantum uncertainties,
accompanying the measurement of mean value of certain basic observables. The
latter are defined in terms of the orthogonal basis of Lie algebra,
corresponding to the dynamic symmetry group. We discuss the relativity of
entanglement with respect to the choice of basic observables and a way of
stabilization of robust entanglement in physical systems.Comment: 7 pages, 1 figure,1 tabe, will be published in special issue of
