摘要
图拓扑指标的研究在化学领域一直占有重要地位,以单圈图为例,研究了其图的Gutman指标和顶点Gutman指标,并给出了单圈图Gutman指标的排序及最值.在此基础上,进一步对顶点间的距离进行了新的拓展和探索,得到了赋权单圈图的Gutman指标.
The research of graph topological index has always played an important role in the field of chemistry.Taking unicyclic graph as an example,the graph Gutman index and vertex Gutman index of its are studied,and the ranking and maximum value of Gutman index of unicyclic graph are given.On this basis,the distance between vertices is further expanded and explored,and the Gutman index of weighted unicyclic graph is obtained.
