    "abstract": "We consider use of collective variables for description of composite fields\nas collective phenomena due to the strong coupling regime. We discuss two\napproaches, where identification of collective variables of complex quantum\nsystem does not depend on knowledge of other degrees of freedom: (a) collective\nvariables as parameters of group transformations changing the path integral of\nthe system, and (b) collective variables as background fields for quantum\nsystem. In the case (a) we briefly present an approach. In the case (b) we\nconsider fermions in an external scalar field, which serves as a collective\nvariable in a nonlinear model for composite scalar field with a finite\ncompositeness scale.",
