理想的星约化与Prufer v-乘法域

Star-reductions of ideals and Prufer v-multiplication domains

E. Houston, S. Kabbaj, A. Miomouni

摘要:

设R是交换环,I是R的理想. I的一个次理想J是I的一个约化,如果对于某个正整数n,JI^n = I^n+1。环R具有(有限)基本理想性质,如果R的(有限生成)理想没有真约化。海斯将(一维)Prufer域刻画为具有有限基本理想性质(基本理想性质)的域。我们将Hays的结果推广到Prufer v-乘法域,用“w-基本”代替“基本”,其中w是一个特殊的星形运算。我们还研究了某些恒星操作的恒星基本性质之间的关系。

英文摘要:

Let R be a commutative ring and I an ideal of R. A sub-ideal J of I is a reduction of I if JI^n = I^n+1 for some positive integer n. The ring R has the (finite) basic ideal property if (finitely generated) ideals of R do not have proper reductions. Hays characterized (one-dimensional) Prufer domains as domains with the finite basic ideal property (basic ideal property). We extend Hays' results to Prufer v-multiplication domains by replacing "basic" with "w-basic," where w is a particular star operation. We also investigate relations among star-basic properties for certain star operations.
