Abstract
It is shown that the construction of the class operator for SU(2) is a partial case of a much more general problem, that of decomposing an o perator into components transforming under conjugation according to a given irreducible representation. The problem is solved generally for arbitrary compact groups and some possibilities for extensions of this procedure to the case of non-compact groups are indicated.
