May 25, 2012 at 0:04	comment	added	Jim Humphreys		The choice of algebraically closed field doesn't really seem to matter here. Also, I think it's safe to assume the group is semisimple (and of course connected, which is implicit). You need semi-simple to make "simply connected" meaningful. This case is treated explicitly in the part of Springer LN 131 written by Springer and Steinberg: II, 5.1, where they note the importance of the simply connected assumption. Finally, I'm not sure what your SO(3,C) means in this context, so I don't quite follow your last sentence.
