证明了k上仿射n-空间上任意特征的域k的加法群的代数群作用的不变量的牛顿多面体的顶点位于坐标超平面上。设E是这些牛顿多面体的顶点位于不同坐标超平面上的所有边的集合。它表明,这些多面体之一,有边的所有方向表示在E。
It is shown that the vertices of Newton polytopes of invariants of an algebraic group action of the additive group of a field k of arbitrary characteristic on affine n-space over k lie on the coordinate hyperplanes. Furthermore, let E be the set of all edges of these Newton polytopes whose vertices lie in different coordinate hyperplanes. It is shown that one of these polytopes has edges with all directions represented in E.
