RATIONALLY TRIANGULABLE AUTOMORPHISMS

[摘要] This paper provides a necessary and sufficient condition for the rational triangulability of actions of the algebraic group G(a) on affine space. The criterion is used to demonstrate the rational triangulability of all G(a) actions on A3(k), as well as to prove, for arbitrary n, that all G(a) actions are stably rationally triangulable.
