| Mar 18, 2015 at 18:47 | comment | added | LSpice | I'm confused by the statement "an abelian subgroup $A$ of the finite group $A$ always lies in a maximal torus of the algebraic group." I assume you mean that it lies there naturally, rather than via some funny embedding? What does this mean for $A$ the unipotent of a Borel in $G = \operatorname{SL}_2$? | |
