• NEW AUGMENTED ZAGREB INDICES
Abstract
We introduce some new augmented Zagreb indices: second, third and fourth augmented Zagreb indices of a molecular graph. A topological index is a numerical parameter mathematically derived from the graph structure. In this paper, we compute augmented zegreb index and Sanskruti index of triangular benzenoid Tn, hexagonal parallelogram nanotube P(m, n) and zigzag-edge coronoid fused with starphene nanotube ZCS(k, l, m) by using the line graphs of the subdivision graphs of these important chemical graphs.
Keywords
augmented Zagreb index, triangular benzenoid, hexagonal parallelogram nanotube, zigzag-edge coronoid fused with starphene nanotube.
