Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
In this research work, we introduce a new version of leap Zagreb index called fourth leap Zagreb index. Mathematical properties and exact values for some standard classes of graphs for this new topological index are obtained. Also, the upper bounds are established. The values of this index for some graph operations containing the Cartesian product, Join and Composition are found.
