| Aug 14, 2014 at 16:04 | comment | added | Roman | Mp(2) acts on functions and hence on distributions on $K^4=gl(2)$ (as well as $K^3=sl(2)$). In fact a bigger group Mp(8) (resp. Mp(6)) acts there (and its central element surely acts but a nontrivial scalar), then the quadratic form $det$ defines a homomorphism $Mp(2)\to Mp(8)$. | |
