Julio B. Clempner,Alexander PoznyakAn . 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.

Lecture Notes in Computer ScienceWe consider an equilibrium state of a system depending on several parameters and assume that (in some domain of variation of the parameters) this equilibrium state does not bifurcate.

,Whitney’s Singularity Theory,In 1955 the American mathematician Hassler Whitney published the article ‘Mappings of the plane into the plane’ laying the foundations for a new mathematical theory of singularities of smooth mappings.

A Catastrophe Machine,In contrast to the example given above the application of singularity theory to the study of bifurcation of equilibrium states in the theory of elasticity is irreproachably founded.
