| Nov 8, 2020 at 10:06 | comment | added | Jason Starr | I should add one qualification: “rational” should be “geometrically rational”. Over any base, the special linear group is rational. | |
| Nov 8, 2020 at 9:57 | comment | added | Jason Starr | Every connected, linear algebraic group is rational (cf. the Bruhat decomposition). Thus the action on the Chow group is trivial. | |
