论文摘要
我们对特征零的代数闭合场上的正常仿射表面上的交换代数单体结构进行了分类。答案用两种语言给出：委员会和Cox坐标。结果来自正常仿射型n上的等级0，n-1或n的交换性单体结构的更一般分类。
We classify commutative algebraic monoid structures on normal affine surfaces over an algebraically closed field of characteristic zero. The answer is given in two languages: comultiplications and Cox coordinates. The result follows from a more general classification of commutative monoid structures of rank 0, n-1 or n on a normal affine variety of dimension n.
