Wealso find the fourth and fifth version of atomic bound connectivity ABC4, ABC5 index and fourth and fifth version of geometric-arithmetic GA4, GA5 index of line graph of 1-subdivided graphs of probabilistic neural networks L[PNN(q,c∗,c)]. Secondly, we find the degree based topological indices and M-polynomial for line graph of m-subdivided graphs for the chain of Bismuth Tri-Iodide L[m−Bil3] for m ≥ 3. Lastly, we find the first and third zagreb eccentric index and M-polynomial of sierpinski networks S(n,k).endepartment of mathematicsDegree-Distance Base Topological Indices from Some Graphs OperationsAqib AliDr. Kashif AliThesis
