The weighted vertex PI index of bicyclic graphs
Discrete Applied Mathematics, 2018 The weighted vertex PI index of a graph G is defined by P I w ( G ) = ∑ e = u v ∈ E ( G ) ( d G ( u ) + d G ( v ) ) ( n u ( e | G ) + n v ( e | G ) ) where d G ( u ) denotes the vertex degree of u and n u ( e | G ) denotes the number of vertices in G ...
