关于Jaco图的Gutman指标的一个注记
A Note on the Gutman Index of Jaco Graphs
摘要：
对连通无向图$G$引入了\emph{Gutman index}的概念，记作$Gut(G)$.本文将这一概念应用于Jaco图族的基础图（\emph{directed graphs by definition}），并给出了\emph{Gutman index} $Gut(J^*_{n+1}(x)).$的一个递归公式。我们还确定了Jaco图之间平凡\emph{edge-joint}的\emph{Gutman index}。
英文摘要：
The concept of the \emph{Gutman index}, denoted $Gut(G)$ was introduced for a connected undirected graph $G$. In this note we apply the concept to the underlying graphs of the family of Jaco graphs, (\emph{directed graphs by definition}), and describe a recursive formula for the \emph{Gutman index} $Gut(J^*_{n+1}(x)).$ We also determine the \emph{Gutman index} for the trivial \emph{edge-joint} between Jaco graphs.
