Local rings of embedding codepth 3: A classification algorithm
mag(2014)
摘要
Let be an ideal of a regular local ring with residue field . The length of the minimal free resolution of is called the codepth of . If it is at most , then the resolution carries the structure of a differential graded algebra, and the induced algebra structure on provides for a classification of such local rings.
