| Sep 6, 2010 at 21:33 | comment | added | Yemon Choi | It may be worth pointing out that in most cases I know of, semigroups of operators are just images of the positive real line. So in that corner of analysis, it's not clear that "representation theory of the real half-line" is that useful a viewpoint. | |
