##### 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. Computing the Narumi-Katayama indices and its modified version of some nanostar dendrimers

*Volume 2, Issue 7 , July 2020, , Pages 771-775*

#####
**Abstract **

Dendrimers are the highly branched organic macromolecules with successive layers or generations of branch units surrounding a central core. In mathematical chemistry, a particular attention has been given to degree-based graph invariant. The Narumi-Katayama index and its modified version of a graph G, ...

##### 3. New results on eccentric connectivity indices of V-Phenylenic nanotube

*Volume 2, Issue 6 , June 2020, , Pages 663-671*

#####
**Abstract **

Topological index is a type of molecular descriptor calculated based on the molecular graph of a chemical compound. Topological indices are used for developing the quantitative structure activity relationships (QSARs) in which the biological activity or other properties of the molecules are correlated ...

##### 4. Study of some topological invariants of subdivided mk graphs

*Volume 2, Issue 6 , June 2020, , Pages 731-738*

#####
**Abstract **

An mk-graph of a graph G can be defined by taking m≥2 copies G1,..., Gm of a graph G in which every vertex ut of copy Gt is adjacent to a corresponding vertex vs of copy Gs. An mk-graph is represented by mk(G). In this research study, we discussed some degree based topological indices (connectivity ...
