摘要:

图的迫零数是图的最小秩的一个下界。本文对某些循环图,包括二部循环图、三次循环图和环面积循环图的迫零数进行了界化和刻画,得到了最小秩和最大零度的界.我们还评估何时迫零数将给出相等。

英文摘要:

It is well-known that the zero forcing number of a graph provides a lower bound on the minimum rank of a graph. In this paper we bound and characterize the zero forcing number of certain circulant graphs, including some bipartite circulants, cubic circulants, and circulants which are torus products, to obtain bounds on the minimum rank and the maximum nullity. We also evaluate when the zero forcing number will give equality.
