Is there an almost-direct product decomposition for disconnected reductive algebraic groups? @Jim Thank you for the additional clarifications on the bigger picture. The natural examples you mentioned are indeed quite helpful. |

Is there an almost-direct product decomposition for disconnected reductive algebraic groups? @Will Thank you for the answer, it is along the lines of what I was looking for. I can see why the connected component of the identity in a nilpotent reductive group is a central torus. However, it isn't clear to me what you mean by the "universal map from the group to a torus" which yields the finite group in the almost-direct product decomposition. Could you perhaps elaborate a bit on this? |
