F-sum图的零阶Randic指数与边度指数

Zero Randic Index and Generalized Edge-degree Index of F-sum Graphs

通过利用F-sum图与子图间度的关系,推导出F-sum图的零阶Randic指数和边度指数的计算公式以及两者之间的关系式,并得到了F-sum图的第一Zagreb指数、Forgotten指数等相应的结果,同时给出了其在化学图论上的应用。

By means of the degree relations between F-sumgraphs and their subgraphs, the formulae of zero Randic index and generalized edge-degree index of F-sum graphs and their relations is derived. We further present the corresponding results on the first Zagreb index, forgotten index and their applications on chemical graph theory.
