ISI(G) Topological Index of Sum Graphs For Some Finite Groups

Abstract

A topological index can convert a great deal of knowledge about a mathematical structure into a concrete number. In theoretical mathematics, the topological indices are crucial. A topological index is a graph‫ـ‬based Recently, unified approaches have been adoptedto study these topological indices in groups. In this work, we look at the generalized ISI index since we can obtain some other topological indices as exceptional cases of sum graphs of groups. These generalized indices reduce the work for calculating some topological indexes differently.
