Vertex PI and Weighted Vertex PI Indices for Generalized Fan Graphs and Generalized Wheel Graphs
摘要
Abstract
In this paper,we solve the problem of computing vertex PI indices and weighted vertex PI indices for generalized fan graphs and generalized wheel graphs.Firstly,the vertices and edges of the graphs are divided according to the symmetry of the graph structure,and the distances of different types of edges corresponding to the vertices are explored by using the method of categorical discussion to obtain their vertex PI indices.Secondly,using the association between vertex PI index and weighted vertex PI index,the degree of the corresponding vertex is investigated and the weighted vertex PI index of this type of graph is inscribed.关键词
