森林边理想的极小胞腔分解

The minimal cellular resolutions of the edge ideals of forests

Margherita Barile, Antonio Macchia

摘要:

基于离散的莫尔斯理论,我们给出了森林边理想的一个最小胞元分解的显式构造。特别地,自由模的生成元是Lyubeznik分解中模的生成元的子集。这一过程可以简化分次贝蒂数和投射维数的计算。

英文摘要:

We present an explicit construction of a minimal cellular resolution for the edge ideals of forests, based on discrete Morse theory. In particular, the generators of the free modules are subsets of the generators of the modules in the Lyubeznik resolution. This procedure allows to ease the computation of the graded Betti numbers and the projective dimension.
