Conjugating representations and related results on semi-simple Lie groups
Introduction.In applying symmetry considerations to quantum mechanics, one is often forced to consider representations T of a symmetry group G by means of Hubert space operators which may be either unitary or conjugate-unitary.Indeed, in some situations there is a well-determined subgroup N of G (necessarily normal and of index 2 …
