设 (R, M) 为具有无限留数场的交换诺特局部环,并假设 I 为 R 中的理想。定义了 I 的约简数(表示为 r (I)),并获得了 R 上的条件,对于每个正则解析扩展 R 的一个理想 I,迫使 r (I)(LESSTHEQ) 1 。给出了几个例子来说明 r (I) 以及它有时与其他概念相关的作用。还讨论了解析展度大于 1 的理想的情况,并研究了涉及 I 生成元关系的 r (I) 的解释。
Let (R, M) be a commutative Noetherian local ring having an infinite residue field and suppose I is an ideal in R. The reduction number of I (denoted r (I)) is defined, and conditions on R which force r (I)(LESSTHEQ) 1 for every regular analytic spread one ideal I of R are obtained. Several examples are given illustrating r (I) and the role it sometimes plays in connection with other concepts. The situation for ideals having analytic spread larger than one is also discussed, and an interpretation of r (I) involving the relations on the generators of I is investigated.
