Abstract |
|
Let G be a quasi-simple algebraic group defined and split over the field k. Let V be a maximal k-split unipotent subgroup of G and Aut (V ) the group of k-automorphism of V . The structure of Aut (V ) is determined and the obstructions to making Aut (V ) algebraic when char k > 3 are made explicit. If G is not of type A2, then Aut (V ) is solvable. |
