On Zagreb coindices and Mostar index of $$TiO_2$$ T i O 2 nanotubes [PDF]

open access: yesScientific Reports, 2023
Topological indices are valuable tools in predicting properties of chemical compounds. This study focuses on degree-based topological indices, which have shown strong correlations with various physico-chemical properties such as boiling points and strain

Mostar index of graphs associated to groups

open access: yesMain Group Metal Chemistry, 2022
A bond-additive connectivity index, named as the Mostar index, is used to measure the amount of peripheral edges of a simple connected graph, where a peripheral edge in a graph is an edge whose one end vertex has more number of vertices closer as ...

Mostar Index of Cycle-Related Structures [PDF]

open access: yesJournal of Chemistry, 2022
A topological index is a numerical quantity associated with the molecular structure of a chemical compound. This number remains fixed with respect to the symmetry of a molecular graph.

A relation between Wiener index and Mostar index for daisy cubes [PDF]

open access: yesDiscrete Mathematics Letters, 2022
Daisy cubes are a class of isometric subgraphs of the hypercubes Q n. Daisy cubes include some previously well known families of graphs like Fibonacci cubes and Lucas cubes. Moreover they appear in chemical graph theory. Two distance invariants, Wiener and Mostar indices, have been introduced in the context of the mathematical chemistry.

Mostar index and bounded maximum degree [PDF]

open access: yesDiscrete Optimization, 2023
Došlić et al. defined the Mostar index of a graph $G$ as $Mo(G)=\sum\limits_{uv\in E(G)}|n_G(u,v)-n_G(v,u)|$, where, for an edge $uv$ of $G$, the term $n_G(u,v)$ denotes the number of vertices of $G$ that have a smaller distance in $G$ to $u$ than to $v$.

Bounding the Mostar index [PDF]

open access: yesDiscrete Mathematics, 2022
Došlić et al. defined the Mostar index of a graph $G$ as $Mo(G)=\sum\limits_{uv\in E(G)}|n_G(u,v)-n_G(v,u)|$, where, for an edge $uv$ of $G$, the term $n_G(u,v)$ denotes the number of vertices of $G$ that have a smaller distance in $G$ to $u$ than to $v$. They conjectured that $Mo(G)\leq 0.\overline{148}n^3$ for every graph $G$ of order $n$.

On the Extremal Weighted Mostar Index of Bicyclic Graphs

open access: yesAxioms
Let G be a simple connected graph with edge set E(G) and vertex set V(G). The weighted Mostar index of a graph G is defined as w+Mo(G)=∑e=uv∈E(G)(dG(u)+dG(v))|nu(e)−nv(e)|, where nu(e) denotes the number of vertices closer to u than to v for an edge uv ...

The Second Maximum Mostar Index of Unicyclic Graphs With Given Diameter

open access: yesJournal of Mathematics
Topological invariants are key tools for studying the physicochemical and thermodynamic properties of chemical compounds. Recently, a new bond-additive distance-based graph invariant called the Mostar index has been developed.
