Molecular descriptors associated with some networks

A topological index, also known as connectivity index, is a molecular structure descriptorcalculated from a molecular graph of a chemical compound which characterizes its topology.Various topological indices are categorized based on their degree, distance, and spectrum. Tostudy the quantitative structure property relationship of molecules, the efficient tools are thetopological indices. The topological indices of certain interconnection networks got attentionof many researchers in the recent years. In this connection, we study the topological invariantsassociated with certain Sudoku networks.
