Spectral Bounds for some Topological Indices

A larger amount of studies reveal that there is strong inherent connection between the chemical characteristics of nanostructures and their molecular structures. Degree-based topological indices introduced on these chemical molecular structures can help material scientists better understand its chemical and biological features, thus they can make up for the lack of chemical experiments. In this paper, we obtain some bounds for some topological indices such as Zagreb indices and Wiener index using the spectral radius of the adjacency matrix of a graph.
