摘要

让 $n\ge 2$ 是一个整数。格里马尔迪图 G(n) 由集合 $\{ 0, \ldots , n-1 \}$的元素作为顶点定义。当且仅当$\gcd (x+y, n) =1$ 时，两个不同的顶点 x 和 y 在 G(n) 中是相邻的。本文将研究这些图的边理想的贝蒂数及其补数。

Betti Numbers of Edge Ideals of Grimaldi Graphs and Their Complements

Let $n\ge 2$ be an integer. The Grimaldi graph G(n) is defined by taking the elements of the set $\{ 0, \ldots , n-1 \}$ as vertices. Two distinct vertices x and y are adjacent in G(n) if and only if $\gcd (x+y, n) =1$. In this paper, we examine the Betti numbers of the edge ideals of these graphs and their complements.
