Two Complex Graph Operations and their Exact Formulations on Topological Properties
Complexity, 2022 Graph operations are utilized for developing complicated graph structures from basic graphs, and these basic graphs can help to understand the properties of complex networks. While on the other side, the topological descriptor is known as a numeric value

On the Reformulated Second Zagreb Index of Graph Operations
Journal of Chemistry, 2021 Topological indices (TIs) are expressed by constant real numbers that reveal the structure of the graphs in QSAR/QSPR investigation. The reformulated second Zagreb index (RSZI) is such a novel TI having good correlations with various physical attributes,

Reformulated First Zagreb Index of Some Graph Operations
Mathematics, 2015 The reformulated Zagreb indices of a graph are obtained from the classical Zagreb indices by replacing vertex degrees with edge degrees, where the degree of an edge is taken as the sum of degrees of the end vertices of the edge minus 2. In this paper, we

Novel Distance-Based Molecular Descriptors for Styrene Butadiene Rubber Structures
JTAM (Jurnal Teori dan Aplikasi Matematika)Styrene-butadiene rubber (SBR) is a general-purpose rubber produced from a copolymer of styrene and butadiene. It is used largely in automobile and truck tires. In general, it is considered to be an abrasion-resistant replacement for natural rubber. In

On reformulated zagreb indices with respect to tricyclic graphs
, 2014 The authors Mili$\breve{c}$evi$\acute{c}$ et al. introduced the reformulated Zagreb indices, which is a generalization of classical Zagreb indices of chemical graph theory. In the paper, we characterize the extremal properties of the first reformulated Zagreb index.

Reformulated Zagreb Indices of Some Cycle-Related Graphs and Linear [n]-Phenylenes
Osmaniye Korkut Ata Üniversitesi Fen Bilimleri Enstitüsü DergisiGraph invariants (topological indices) are numerical values of graphs obtained from 2-dimensional (2-D) images of chemical structures. These invariants are used in the structure-property/activity studies to predict certain properties such as the enthalpy of vaporization, and stability of molecular structures. In this paper, reformulated Zagreb indices,
