A self-map F of an affine space ${\bf A}_k^n $ over a field k is said to be a Keller map if F is given by polynomials F 1 , …, F n ∈ k [X 1 , …, X n ] whose Jacobian determinant lies in $k\setminus \{0\}$ . We consider char(k ) = 0 and assume, as we may, that the F i s vanish at the origin. In this note, we prove that if F is Keller then its base ideal I F = 〈F 1 , …, F n 〉 is radical (a finite intersection of maximal ideals in this case). We then conjecture that I F = 〈X 1 , …, X n 〉, which we show to be equivalent to the classical Jacobian Conjecture. In addition, among other remarks, we observe that every complex Keller map admits a well-defined multidimensional global residue function.

凯勒图的理想理论方法
自我地图F 仿射空间${\bf A}_k^n $ 在一个领域ķ 被称为凯勒图,如果F 由多项式给出F 1 , …,F n ∈ķ [X 1 , …,X n ] 其雅可比行列式位于$k\setminus \{0\}$ . 我们考虑 char(ķ ) = 0 并且我们可以假设F 一世 s 消失在原点。在本笔记中,我们证明如果F 是凯勒,那么它的基本理想一世 F = 〈F 1 , …,F n 〉是激进的(在这种情况下是最大理想的有限交集)。然后我们推测一世 F = 〈X 1 , …,X n 〉,我们证明它等价于经典的雅可比猜想。此外,在其他评论中,我们观察到每个复杂的 Keller 映射都承认一个定义明确的多维全局残差函数。
