摘要:

连通图$G$的边超Wiener指标定义为$WW_e(G) = \frac{1}{2}\sum_{\lbrace e,f\rbrace \subseteq E(G)}d(e,f) + \frac{1}{2}\sum_{\lbrace e,f\rbrace \subseteq E(G)}d(e,f)^2$。部分立方体是一类有着广泛应用的图,本文提出了一种计算其边超Wiener指数的方法。它还显示了如何该方法可以应用到树。此外,得到了计算苯型体系的边超Wiener指数的算法。最后,该算法被用来纠正已知的闭公式的边Wiener指数和边超Wiener指数的线性多并苯。

英文摘要:

The edge-hyper-Wiener index of a connected graph $G$ is defined as $WW_e(G) = \frac{1}{2}\sum_{\lbrace e,f\rbrace \subseteq E(G)}d(e,f) + \frac{1}{2}\sum_{\lbrace e,f\rbrace \subseteq E(G)}d(e,f)^2$. We develop a method for computing the edge-hyper-Wiener index of partial cubes, which constitute a large class of graphs with a lot of applications. It is also shown how the method can be applied to trees. Furthermore, an algorithm for computing the edge-hyper-Wiener index of benzenoid systems is obtained. Finally, the algorithm is used to correct already known closed formulas for the edge-Wiener index and the edge-hyper-Wiener index of linear polyacenes.
