Mordechai Katzman

摘要:

本文研究了完全局部环的剩余域的内射壳上的Frobenius映射,目的是对源于紧闭包理论的对象提供构造性的描述.具体而言,本文描述了算法计算参数测试理想,和紧封闭的内射壳的剩余域的一类良好的表现环,其中包括所有准Gorenstein完全局部环的某些子模块。

英文摘要:

This paper studies Frobenius maps on injective hulls of residue fields of complete local rings with a view toward providing constructive descriptions of objects originating from the theory of tight closure. Specifically, the paper describes algorithms for computing parameter test ideals, and tight closure of certain submodules of the injective hull of residue fields of a class of well-behaved rings which includes all quasi-Gorenstein complete local rings.
