Abstract
An mk-graph of a graph G is defined by taking m ≥ 2 copies G1, … , Gm of a graph G in which every vertex uh of copy Gh is adjacent to a corresponding vertex vm of copy Gm. An mk-graph is represented by mk(G). In this paper we work on some degree based connectivity indices of subdivided mk-graph generated by ladder and triangular ladder graph. Also closed formulas for computing various degree based topological indices of said families of graphs have been presented.
