Oct 12, 2022 at 14:25 | comment | added | LSpice | Re, there's so much good math about algebraic groups in Borel and Tits - Groupes réductifs and the compléments that it's worth learning enough French to read it. Reading mathematical French is very easy compared to reading general French or math in another language, at least for me as a very monoglot English speaker. | |

Aug 23, 2022 at 22:44 | comment | added | zom | @naf Thank you, but I don’t understand French, so I culdn’t get it. Is it simple? | |
Aug 22, 2022 at 7:47 | comment | added | naf | See Section 6.21 (ii) of the paper "Groupes Reductifs" by Borel and Tits. | |
Aug 22, 2022 at 2:47 | comment | added | Jason Starr | @HYL The additive group is not a simple algebraic group (it is not semisimple, it is not reductive, … ). | |
Aug 22, 2022 at 2:36 | comment | added | HYL | The Weil restriction of $\mathbf{A}^1_F$ is $\mathbf{A}^d_{\mathbf{Q}}$ where $d = [F:\mathbf{Q}]$. | |
