Popis:	The Landau-Ginzburg-Wilson Hamiltonian is a function that relates Landau's phenomenological theory of magnetic phase transitions to the quantum mechanics of a microscopic spin model. The authors study how the symmetry of the system under consideration manifests itself in these different descriptions of the thermodynamic properties (density operator, LGW Hamiltonian, other functions of the order parameters). The results of this discussion are used to comment on divergent opinions in the literature concerning the use of corepresentations in magnetic phase transitions.
