Methods of catastrophes theory in the phenomenology of phase transitions

The monograph is devoted to the presentation of the methods of catastrophes theory and the construction based on these methods of phenomenological models of phase transitions in solid bodies. Methods of constructing structurally stable normal forms of functions, including functions on which symmetry conditions are imposed. A classification of phenomenological models of phase transitions for two interacting one -component parameters of order, two -component and three -component parameters of the order in the number of control parameters varied in the experiment. Theoretical dependencies of the abnormalities of the physical properties of models are compared with experimental data in segnelectric, magnetics, solid solutions of rare -earth metals, multi -spheres and other solid bodies experiencing phase transitions.
