WebThere seem to be two different things one must consider when representing a symmetry group in quantum mechanics: The universal cover: For instance, when representing the rotation group $\mathrm{SO}(3)$, it turns out that one must allow also $\mathrm{SU}(2)$ representations, since the negative sign a "$2\pi$ rotation" induces in $\mathrm{SU}(2)$ … Webtions form an abelian category, have enough injectives, etc. It has more structure: it’s a Lie group, it’s an algebraic group (meaning it’s a variety with compatible multiplication).
