The facet ideals of matching complexes of line graphs

Guangjun Zhu, Hong Wang, Yijun Cui

摘要:

设$L_n$是一个具有$n$边的线图,$\F(L_n)$是其匹配复形的刻面理想.本文给出了$\F(L_n)$的不可约分解以及$\F(L_n)$的投射维数和正则性的精确公式。

英文摘要:

Let $L_n$ be a line graph with $n$ edges and $\F(L_n)$ the facet ideal of its matching complex. In this paper, we provide the irreducible decomposition of $\F(L_n)$ and some exact formulas for the projective dimension and the regularity of $\F(L_n)$.
