仿射平面上的自同构定理与加性群作用
The automorphism theorem and additive group actions on the affine plane
摘要:
由于Rentschler,Miyanishi和Kojima,${\bf G}_a$ -作用在任意域上的仿射平面上的不变环由一个坐标生成。本文利用Jung和van der Kulk的自同构定理给出了这个结果的一个新的简短证明。
英文摘要:
Due to Rentschler, Miyanishi and Kojima, the invariant ring for a ${\bf G}_a$-action on the affine plane over an arbitrary field is generated by one coordinate. In this note, we give a new short proof for this result using the automorphism theorem of Jung and van der Kulk.
