Comparative Study of Prism Octahedron Network via Eccentric Invariants

Journal of Chemistry, 2023
Topological indices are empirical features of graphs that characterize the topology of the graph and, for the most part, are graph independent. An important branch of graph theory is chemical graph theory.

On Computation Degree-Based Topological Descriptors for Planar Octahedron Networks

Journal of Mathematics, 2021
A molecular graph is used to represent a chemical molecule in chemical graph theory, which is a branch of graph theory. A graph is considered to be linked if there is at least one link between its vertices.
