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

The Upper Bound of the Edge Mostar Index with Respect to Bicyclic Graphs

open access: yesMathematics, 2023
Let G be a connected graph; the edge Mostar index Moe(G) of G is defined as Moe(G)=∑e=uv∈E(G)|mu(e)−mv(e)|, where mu(e) and mv(e) denote the number of edges in G that are closer to vertex u than to vertex v and the number of edges that are closer to ...

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 ...

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 Mostar and Wiener index of Alternate Lucas Cubes [PDF]

open access: yesTransactions on Combinatorics, 2023
The Wiener index and the Mostar index quantify two distance related properties of connected graphs: the Wiener index is the sum of the distances over all pairs of vertices and the Mostar index is a measure of how far the graph is from being distance ...

On Mostar and Edge Mostar Indices of Graphs

open access: yesJournal of Mathematics, 2021
Let G be a graph with edge set EG and e=uv∈EG. Define nue,G and mue,G to be the number of vertices of G closer to u than to v and the number of edges of G closer to u than to v, respectively. The numbers nve,G and mve,G can be defined in an analogous way.
