Abstract: | The renormalization group is applied to the generating functional of connected Green functions of composite fields. Conditions for composite field condensation are formulated for the β and γ functions in a new renormalization scheme. The vacuum expectation value of a composite field is given completely in terms of the renormalization group parameters. As an example the formalism is applied to the Gross-Neveu model. |
