##### On leap eccentric connectivity index of thorny graphs

*Volume 2, Issue 10 , October 2020, , Pages 1033-1039*

#####
**Abstract **

The 2-degree of a vertex v of a simple graph G is the number of vertices which are at distance two from v in G and is denoted by d2(v). In this article, we compute exact values of a ...

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

*Volume 2, Issue 8 , August 2020, , Pages 841-846*

#####
**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 ...

##### 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 ...
