As well as the usual "proper Lorentz group" there is Ungar's proper-time proper-velocity Lorentz group, which could also be called for short "proper Lorentz group".

| Nov 26, 2010 at 17:20 | comment | added | José Figueroa-O'Farrill | One possible answer to this question is that the Lorentz group (in dimension at least 3) is semisimple and not compact, and it is a somewhat paradigmatic example. The Lorentz group is dimension 4 (which is what is treated in Bargmann's paper) is locally isomorphic to $SL(2,\mathbb{C})$. Perhaps this group plays a similarly motivating rôle as $SU(2)$ plays in studying the representation theory of compact Lie groups. | |
