Construction of Petersen graph via graph product and correlation of topological descriptors of Petersen graph in terms of cyclic graph C-5

, 2022
Graph product yields a new structure from two initial given structures. The computation of topological indices for these sophisticated structures using the graph product is a critical endeavor. Petersen graph is a structure which consists of ten vertices

Inverse problem for Zagreb indices

, 2018
The inverse problem for integer-valued topological indices is about the existence of a graph having its index value equal to a given integer. We solve this problem for the first and second Zagreb indices, and present analogous results also for the ...

Reformulated F-index of graph operations

, 2017
The first general Zagreb index is defined as $M_1^\lambda(G)=\sum_{v\in V(G)}d_{G}(v)^\lambda$ where $\lambda\in \mathbb{R}-\{0,1\}$‎. ‎The case $\lambda=3$‎, ‎is called F-index‎.

Relations between the first and second Zagreb indices of subdivision graphs

, 2018
The first and second Zagreb indices of a graph are two of the topological invariants used in molecular calculations by Mathematicians and Chemists. First Zagreb index and multiplicative Zagreb indices, all versions of Zagreb indices of subdivision graphs,

On the topological indices and graph operation

As we know that some chemically interesting graphs can be obtained by different graph operations on some general or particular graphs, it is important to study such graph operations in order to understand how it is related to the corresponding ...
