The inherent qualities of carbon nanosheets that come from their underlying molecular
structure have drawn an enormous amount of interest from researchers. Molecular …

The cut method is a powerful tool for the investigation of distance-based (and some other)
molecular structure-descriptors. In this paper a survey on the recent developments of the …

In the past few years, two-dimensional (2D) layered nanomaterials have greatly attracted the
scientific community. Among 2D nanomaterials, the porphyrin-based Naphtalenic …

Topological indices and domination in graphs are the essential topics in the theory of
graphs. A set of vertices D⊆ V (G) is said to be a dominating set for G if any vertex v∈ VD is …

For a given graph G, the well-known Randić index of G, introduced by Milan Randić in 1975,
is defined as R (G)=∑ uv∈ E (G)(dudv)− 1/2, where the sum is taken over all edges uv and …

A graph invariant is a numerical value that depicts the structural properties of an entire
graph. The Wiener index is the oldest distance based graph invariant which is defined as the …

Studies on the information content of graphs and networks have been initiated in the late
fifties based on the seminal work due to Shannon and Rashevsky. Various graph …

The vertex PI index $ PI (G)=\sum_ {xy\in E (G)}[n_ {xy}(x)+ n_ {xy}(y)] $ is a distance-based
molecular structure descriptor, where $ n_ {xy}(x) $ denotes the number of vertices which …

Abstract Recently, Ammar Alsinai et al.,[1], introduced Reciprocal leap Zagreb indices of a
graph based on the inverse second degree of vertices. The first Reciprocal leap Zagreb …

In this paper, we computed the topological indices of pent‐heptagonal nanosheet. Formulas
for atom‐bond connectivity index, fourth atom‐bond connectivity index, Randić connectivity …
