Weighted Vertex PI Index for Some Special Graphs
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 8
Abstract
The Padmakar-Ivan (PI) index is a Wiener-Szeged-like topological index which reflects certain structural features of organic molecules. Each structural feature of such organic molecule can be expressed as a graph. In this paper, we study the weighted vertex PI indices for some special graphs, such as Ir (Fn), Ir(Wn), , , Ir( ) and Ir( ). Keywords: weighted vertex, PI indices, fan graph, wheel graph, gear fan graph, gear wheel graph, r-corona graph.
