Bifurcations of Equilibrium States,An . is described mathematically by a vector field in phase space. A point of phase space is called a . of the system. The vector at this point indicates the speed of change of the state.

Singularities of Accessibility Boundaries,A . in phase space is defined as follows: at every point of the space we have not one velocity vector (as in the usual evolutionary system) but a whole set of vectors called the . (Fig. 49).

How did it come about? Zel’dovich in 1970 proposed an explanation of the formation of particle clusters that is mathematically equivilent to the analysis the forma
