Cohen-Macaulay单项商环的胞腔分解

Cellular resolutions of Cohen-Macaulay monomial quotient rings

Gunnar Floystad

摘要:

研究了胞腔复形上的单项式标记,给出了这些单项式所生成的理想的最小细胞分辨,使得相关的商环是Cohen-Macaulay.我们引入这样的标签是最大的概念。每个胞腔复形的最大标号只有有限的数目,我们将这些分类为树,部分为多边形的细分,并为某些类的自对偶多面体。

英文摘要:

We investigate monomial labellings on cell complexes, giving a minimal cellular resolution of the ideal generated by these monomials, and such that the associated quotient ring is Cohen-Macaulay. We introduce a notion of such a labelling being maximal. There is only a finite number of maximal labellings for each cell complex, and we classify these for trees, partly for subdivisions of polygons, and for some classes of selfdual polytopes.
