A Novel Approach to Modified Heinz-Quarter Mean Labeled NM-Polynomial and Topological Indices of Chemical Graphs

NM-polynomial is an extension of the classical M-polynomial and is based on Neighborhood -related vertex parameters. This polynomial provides a compact representation of the structural properties of a graph. This polynomial is useful in chemical graph theory for predicting physical properties .It incorporates both labeling information and graph topology leading to more informative molecular descriptors. A topological index is a function from the collection of graphs to the set of real numbers that describe the topology of the graph and are used in QSPR / QSAR analysis. They play an important role in the study of QSPR/QSAR. In this article, we introduced Modified Heinz-Quarter Mean labeling and Modified Heinz-Quarter Mean Labeled NM-Polynomial through Neighborhood label sums and compute some induced Topological Indices of chemical structures.
