چکیده
|
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, weobtained some explicit expressions of eccentricity version of findex 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.
