A topological index is a function having set of graphs as its domain and real numbers range. Here we concentrated on indices involving the number vertices, edges maximum minimum vertex degree. The aim this paper to compute lower upper bounds second Zagreb index, third Hyper Harmonic Redefined first First reformulated Forgotten square F-index, Sum-connectivity Randic Reciprocal Gourava Sombar Ni...
Molecular topology allows describing molecular structures following a two-dimensional approach by taking into account how the atoms are arranged internally through connection matrix between that part of structure. Various indices (unique for each molecule) can be determined, such as Zagreb, Balaban, and topological indices. These have been correlated with physical chemistry properties weight, b...
The study of networks such as Butterfly networks, Benes interconnection David-derived through graph theoretical parameters is among the modern trends in area theory. Among these tools, topological Indices TIs have been frequently used invariants....
By d(v|G) and d_2(v|G) are denoted the number of first and second neighborsof the vertex v of the graph G. The first, second, and third leap Zagreb indicesof G are defined asLM_1(G) = sum_{v in V(G)} d_2(v|G)^2, LM_2(G) = sum_{uv in E(G)} d_2(u|G) d_2(v|G),and LM_3(G) = sum_{v in V(G)} d(v|G) d_2(v|G), respectively. In this paper, we generalizethe results of Naji et al. [Commun. Combin. Optim. ...
