某些网络上的测地线横截问题

The geodesic transversal problem on some networks

Paul Manuel, Bostjan Bresar, Sandi Klavzar

摘要:

一个图G的顶点集S是G的测地线断面,如果G的每一条极大测地线至少包含S的一个顶点。我们确定了某些互连网络(如树的网格)和一些众所周知的化学结构(如硅酸盐网络和碳纳米片)中的最小测地线断面。相应的图不变量的一些有用的一般界限,沿途获得。

英文摘要:

A set S of vertices of a graph G is a geodesic transversal of G if every maximal geodesic of G contains at least one vertex of S. We determine a smallest geodesic transversal in certain interconnection networks such as mesh of trees, and some well-known chemical structures such as silicate networks and carbon nanosheets. Some useful general bounds for the corresponding graph invariant are obtained along the way.
