| Aug 28 at 19:08 | comment | added | Jason Starr | I am certain that they also list the citation to Weil’s original article (although I don’t recall it at this moment). | |
| Aug 28 at 19:07 | comment | added | Jason Starr | That is explained completely in “N’eron models” by Bosch, Luetkebohmert, and Raynard. | |
| Aug 28 at 16:53 | comment | added | Ariyan Javanpeykar | Bounded degree is indeed automatic, because your G is an algebraic group. Also, have a look at [25] and [35] cited in Cantat's paper. | |
| Aug 28 at 16:50 | comment | added | Ariyan Javanpeykar | I just remembered another useful reference: see arxiv.org/abs/1204.1799 | |
| Aug 28 at 12:26 | comment | added | Li Yutong | Thank you! In Cantat's paper, he needs $G$ to have a bounded degree to do the regularization. Since my $G$ is connected, the degree of each element of $G$ should be bounded, right? | |
