##### 4. Theoretical study of benzene ring embedded in P-type surface in 2d network using some new degree based topological indices via M-polynomial

*Volume 3, Issue 3 , March 2021, , Pages 180-186*

#####
**Abstract **

Algebraic polynomials play an important role in theoretical chemistry because these can reflect the properties of the chemical compound. M-polynomial is also an algebraic polynomial that is used to find the expressions of several degree dependent topological indices. These topological indices have the ...

##### 5. Weighted entropies of HAC5C7[p;q] nanotube

*Volume 3, Issue 1 , January 2021, , Pages 1-5*

#####
**Abstract **

The aim of this article was to compute weighted entropy of some well-known nanostructure HAC5C7[p;q]. We applied probability density function to formulate entropy by taking different topological indices as edge weights for example Zagreb indices, modified Zagreb indices, augmented Zagreb index and Randić ...

##### 6. Weighted entropies of Tuc5c8[P;Q] nanotube with the degree based topological indices as weights

*Volume 3, Issue 1 , January 2021, , Pages 14-18*

#####
**Abstract **

The entropy of a graph is a function depending both on the graph itself and on a probability distribution on its vertex set. This graph function originated in the problem of source coding in information theory and was introduced by J. Krner in 1973. Although the notion of graph entropy has its roots ...
