Abstract

The Mostar index

M o (G)

is the sum of absolute values of the differences between

n_{u} (e)

and

n_{v} (e)

over all edges

e = u v

of G, where

n_{u} (e)

and

n_{v} (e)

are the number of vertices of G lying closer to vertex u than to vertex v and the number of vertices of G lying closer to vertex v than to vertex u, respectively. In this article, for given cata-condensed hexagonal systems with p hexagons, which have exactly two full-hexagons, we determine the extremal hexagonal system with the greatest Mostar index, and the corresponding formula of Mostar index is given.

相对于莫斯塔尔指数，具有两个全六角形的极值卡塔缩合苯并呋喃

莫斯塔尔指数 Mo(G)是 G 的所有边 e=uv 上 nu(e)和 nv(e)之差的绝对值之和，其中 nu(e)和 nv(e)分别是 G 中靠近顶点 u 而不是顶点 v 的顶点数，以及 G 中靠近顶点 v 而不是顶点 u 的顶点数。本文针对具有 p 个六边形且恰好有两个全六边形的卡塔缩合六边形系统，确定了莫斯塔尔指数最大的极值六边形系统，并给出了相应的莫斯塔尔指数公式。
