On degree based topological indices of bridge graphs.

In 2009, T. Mansour, M. Schork, introduce the concept of bridge graphs. A bridge graph B(G1, G2, ... , Gm) = B(G1, G2, ... , Gm; v1, v2, ... , vm) of with respect to the vertices is the graph obtained from the graphs G1; G2; ... ; Gm by connecting the vertices vi and vi+1 by an edge for all I = 1; 2; ... ; m-1. In this paper, we determine hyper-Zagreb index, first multiple Zagreb index, second multiple Zagreb index, Zagreb polynomials and M-polynomial for nano structures of bridge graphs.
