Mostar index: Results and perspectives

Applied Mathematics and Computation, 2021
The Mostar index is a recently introduced bond-additive distance-based graph invariant that measures the degree of peripherality of particular edges and of the graph as a whole. It attracted considerable attention, both in the context of complex networks and in more classical applications of chemical graph theory, where it turned out to be useful as a ...

ON MOSTAR INDEX OF GRAPHS

Advances in Mathematics: Scientific Journal, 2021
On the great success of bond-additive topological indices like Szeged, Padmakar-Ivan, Zagreb, and irregularity measures, yet another index, the Mostar index, has been introduced recently as a peripherality measure in molecular graphs and networks. For a connected graph G, the Mostar index is defined as $$M_{o}(G)=\displaystyle{\sum\limits_{e=gh\epsilon

Mostar index

Journal of mathematical chemistry, 2018
We propose and investigate a new bond-additive structural invariant as a measure of peripherality in graphs. We first determine its extremal values and characterize extremal trees and unicyclic graphs. Then we show how it can be efficiently computed for large classes of chemically interesting graphs using a variant of the cut method introduced by Klav ...

Computation of Mostar index for some graph operations

International Journal of Quantum Chemistry, 2021
AbstractVery recently, a novel bond‐additive topological descriptor named as the Mostar index has been proposed as a measure of peripherality in networks and graphs. In this article, we compute the Mostar index of generalized Hierarchical product, lexicographic product, Cartesian product, corona product, join, subdivision vertex‐edge join and Indu–Bala

Extremal phenylene chains with respect to the Mostar index

Discrete Mathematics, Algorithms and Applications, 2021
For a connected graph [Formula: see text], the Mostar index is defined as [Formula: see text], where [Formula: see text] (respectively, [Formula: see text]) is the number of vertices of [Formula: see text] closer to [Formula: see text] (respectively, [Formula: see text]) than [Formula: see text] (respectively, [Formula: see text]).

On the Difference of Mostar Index and Irregularity of Graphs

Bulletin of the Malaysian Mathematical Sciences Society, 2020
For a connected graph the irregularity irr (G) are G, the Mostar index Mo(G) and defined as Mo(G) = uv∈E(G) |n u − n v | and irr (G) = uv∈E(G) |d u − d v |, respec- tively, where d u is the degree of the vertex u of G and n u denotes the number of vertices of G which are closer to u than to v for an edge uv.

On Edge Mostar Index of Graphs

2020
The edge Mostar index 𝑀𝑜𝑒(𝐺) of a connected graph 𝐺 is defined as 𝑀𝑜𝑒(𝐺)=Σ𝑒=𝑢𝑣∈𝐸(𝐺) |𝑚𝑢(𝑒|𝐺)−𝑚𝑣(𝑒|𝐺)|, where 𝑚𝑢(𝑒|𝐺)and 𝑚𝑣(𝑒|𝐺) are, respectively, the number of edges of 𝐺 lying closer to vertex 𝑢 than to vertex 𝑣 and the number of edges of 𝐺 lying closer to vertex 𝑣 than to vertex 𝑢. In this paper, we determine the extremal values of edge Mostar index
