Sometimes physicists and even chemists working on problems in quantum mechanics will say that they are using "group theory" to do a calculation. Upon probing more deeply, I have come to realize that they are really doing representation theory, often of SU
, rather than anything a mathematician would call "group theory". Can anyone explain the relevance of representation theory to quantum mechanics?
