The Wigner–Eckart theorem and covariant operators
A. U. Klimyk
Abstract:
We study matrix elements that depend on functions in the Schwartz space of operators that are
covariant with respect to a group (operators of the type of scalar field operators). We show
that the matrix elements of such operators can be factorized in a weak sense into the Clebsch–Gordan coefficients of the group and reduced matrix elements.
