Distance-based topological indices of tensor product of graphs

Let g and h be connected graphs. the tensor product g + h is a graph with vertex set v(g+h) = v (g) ? v(h) and edge set e(g + h) ={(a , b)(x , y)| ax ? e(g) & by ? e(h)}. the graph h is called the strongly triangular if for every vertex u and v there exists a vertex w adjacent to both of them. in this article the tensor product of g + h under some distance-based topological indices are investigated, when h is a strongly triangular graph. as a special case most of results given by hoji, luob and vumara in [wiener and vertex pi indices of kronecker products of graphs, discrete appl. math., 158 (2010), 1848-1855] will be deduced.
