具有2个平凡距离理想的图

On graphs with 2 trivial distance ideals

Carlos A. Alfaro

摘要:

距离理想推广了图的距离矩阵的Smith标准形。具有2个平凡距离理想的图族包含距离矩阵至多有2个不变因子等于1的图族。本文给出了具有2个平凡距离理想的图的禁止诱导子图的无限族。这些也与其他众所周知的图形类有关。

英文摘要:

Distance ideals generalize the Smith normal form of the distance matrix of a graph. The family of graphs with 2 trivial distance ideals contains the family of graphs whose distance matrix has at most 2 invariant factors equal to 1. Here we give an infinite family of forbidden induced subgraphs for the graphs with 2 trivial distance ideals. These are also related with other well known graph classes.
