M-polynomial based topological properties of Sudoku graphs

Abstract

Geo [J. Appl. Math. Comput, 99-117, 117, (2017)] computed exactly three degree-based topological indices of the Sudoku graphs. As an extention of this study, we prove the M-polynomial of the Sudoku graphs and obtain the mathematical expressions for various topological indices which base on the M-polynomial.
