Abstract

The eccentricity version F-index of a graph G is defined as the summation of cube of all the vertex eccentricities of G. In this report, the eccentricity version of F-index of the generalized hierarchical product of graphs was computed. Further, we obtained some explicit expressions of eccentricity version of F-index for S-sum graphs, Cartesian product graphs and cluster product graphs. Hence applying those outcomes, we arrived at the eccentricity version of F-index for Chemical graphs and nanostructures.
