Shultz polynomial and modified shultz polynomial of certain special molecular graphs

Yun Gao, Li Liang, Wei Gao

Chemical compounds and drugs are often modeled as graphs where each vertex represents an atom of molecule, and covalent bounds between atoms are represented by edges between the corresponding vertices. This graph derived from a chemical compounds is often called its molecular graph, and can be different structures. In this paper, we determine the Shultz polynomial andmodified Shultz polynomial of fanmolecular graph, wheel molecular graph, gear fan molecular graph, gear wheel molecular graph, and their r-corona molecular graphs.
