摘要

设S是一个Gorenstein局部环,并设M是余维c的有限生成Cohen-Macaulay S模。给定正则序列f1,…在M的湮灭子中,设R = S/(f1,…), fc),构建M的分层无s和无r分辨率。该构造归纳地将问题简化为余维c1的Cohen-Macaulay模的情况,并导致M的更高矩阵分解的归纳构造。在M是S上有限射影维数的某个模块的足够高的r -协同的情况下,层分辨率是最小的,并且与我们在[EP]中描述的由更高的矩阵分解定义的分辨率一致。

Layered resolutions of Cohen–Macaulay modules
Let S be a Gorenstein local ring and suppose that M is a finitely generated Cohen-Macaulay S-module of codimension c. Given a regular sequence f1, . . . , fc in the annihilator of M we set R = S/(f1, . . . , fc) and construct layered S-free and R-free resolutions of M . The construction inductively reduces the problem to the case of a Cohen-Macaulay module of codimension c 1 and leads to the inductive construction of a higher matrix factorization for M . In the case where M is a su ciently high R-syzygy of some module of finite projective dimension over S, the layered resolutions are minimal and coincide with the resolutions defined from higher matrix factorizations we described in [EP].
