The symmetric division degree $SDD$-index of a simple connected graph $G$ is defined as the sum of terms $f(d_u,d_v)=(d_u/d_v)+(d_v/d_u)$ over all pairs of distinct adjacent vertices of $G$; where $d_u$ denotes the degree ...

A topological index is a special number which describes the whole structure of a graph.The topological indices are categorized on the basis of their logical roots from topological invariant. A topological index which depends ...

Let G be a graph, the distance d(u,v) between two vertices u and v of G is the minimum length of the paths connecting them. The aim of this paper is computing the distance matrix of infinite familiy of fullerene graph A10n.

Using density functional theory calculations, we investigated properties of a functionalized carbon nanotube with one mercarzole molecule as a benzimidazole fungicide. Three different configurations are possible depending ...

Recently [18], Shigehalli and Kanabur have introduced two new topological indices namely, AG2 index and SK3 index. Hosamani [14], has studied a novel topological index, namely the Sanskruti index S (G) of a ...

In this paper, we study the edge version of some degree based topological indices such as general sum-connectivity index, Randic index, inverse sum indeg index, symmetric division deg index, augmenting Zagreb index and ...

A topological index is a numerical invariant associated with a chemical graph. In this paper we introduce some GAP programs for computing well-known topological indices.

In this paper domination number, vertex-edge domination number and edge-vertex domination are calculated for regular dendrimers.
