| Feb 25, 2021 at 10:06 | comment | added | Mikhail Borovoi | In Question 2 for a connected reductive group $G$ over an algebraically closed field $F$ of characteristic 0, the answer is Yes. | |
| Feb 25, 2021 at 9:56 | comment | added | Mikhail Borovoi | In Question 1, if $F$ is a local field ($\Bbb R$, or $\Bbb C$, or a $p$-adic field), then the answer is Yes for any connected algebraic group $G$, not necessarily reductive or linear. | |
| Feb 25, 2021 at 9:42 | comment | added | Mikhail Borovoi | In Question 1, do you mean the square map on $F$-points $G(F)\to G(F)$? | |
