论文摘要
令K为代数封闭的字段。我们证明，两个变量中的多项式k衍生$ d $在且仅当多项式k-自动形态的亚组与d通勤的d允许元素任意大的元素时。
Let K be an algebraically closed field. We prove that a polynomial K-derivation $D$ in two variables is locally nilpotent if and only if the subgroup of polynomial K-automorphisms which commute with D admits elements whose degree is arbitrary big.
