CHANGE OF VARIABLES AND EQUIVALENCE THEOREMS IN QUANTUM FIELD THEORIES
Technical Report
·
OSTI ID:4043500
The theorem proposed by Chisholm that the S-matrix in quantum field theories remains unchanged under any point transformation of field operators is discussed. A proof of the theorem is presented within the framework of the conventional canonical formalism of field theories. On the basis of the theorem, most of the ordinary equivalence theorems in field theories can be obtained by trivial changes of variables in the Lagrangians. The eqthvalence theorem for the Yang-Mills field is discussed in detail. (D.L.C.)
