##### 1. Multiplicative leap Zagreb indices of T-thorny graphs

*Articles in Press, Accepted Manuscript, Available Online from 30 May 2020*

#####
**Abstract **

Let G=(V, E) is a molecular graph in which the vertex set V represents atoms and the edge set E represents the bonds between the atoms, corresponding to a chemical compound. In this research study, we introduced a new type of distance based topological indices called multiplicative leap Zagreb indices ...

##### 2. F-leap index of some special classes of bridge and chain graphs

*Volume 2, Issue 7 , July 2020, , Pages 827-833*

**Abstract **

The 2-degree of a vertex v in a (molecular) graph G is the number of vertices which are at distance two from v in G. The F-leap index of a molecular graph G is the sum of cubes of the 2-degree of every vertex v in G. In this research study, we have computed the F-leap index of some special classes of ...
