Inverse sum indeg index of graphs
The inverse sum indeg index of a simple graph is defined as the sum of the terms over all edges of where denotes the degree of a vertex of In this paper, we present several upper and lower bounds on the inverse sum indeg index in terms of some molecular structural parameters and relate this index to...
