A real-number to molecular structure mapping is a topological index. It graph invariant method for describing physico-chemical properties of structures specific substances. In that article, We examined pentacene’s chemical composition. The research on the subsequent indices reflected in our paper, we conducted an analysis several including general randic connectivity index, first zagreb sum-con...
The difference of Zagreb indices a graph G is defined as ΔM(G)=∑u∈V(G)(d(u))2−∑uv∈E(G)d(u)d(v), where d(x) denotes the degree vertex x in G. A Halin that results from plane tree T without vertices two and with at least one three such all leaves are joined through cycle C embedded order. In this paper, we establish both lower upper bounds on for general graphs some special fewer inner vertices. ...
We study eccentricity-based indices such as Zagreb eccentricity indices, general index and total index. present exact values of generalized networks related to binary $m$-ary trees, where $m \ge 2$.
