Total edge-betweenness centrality measure of a graph

Arab Journal of Basic and Applied Sciences
Edge-betweenness centrality measure is an important centrality measure that focuses on the role of edges in a graph. The total edge-betweenness centrality measure (EBCM) of a graph is defined as the sum of the edge-betweenness centrality measures of all ...

Sombor Index, Randic Index, and Forgotten Index of Fuzzy Coprime Graph on Dihedral Group

InPrime
This research investigates the topological indices—Sombor, Randic, and Forgotten—of the fuzzy coprime graph constructed from dihedral groups. These indices, which quantify graph structural properties, have important applications in mathematical ...

New bounds on Zagreb connection indices for trees with fixed domination number

AKCE International Journal of Graphs and Combinatorics
A set D of vertices in a graph G is a dominating set of G if every vertex not in D is adjacent to a vertex in D. The domination number, [Formula: see text], is the minimum cardinality among all dominating sets of G.

On the vv-degree based first Zagreb index of graphs

AKCE International Journal of Graphs and Combinatorics
A topological index is a graph invariant applicable in chemistry. The first Zagreb index is a topological index based on the vertex degrees of molecular graphs. For any graph G, the first Zagreb index [Formula: see text] is equal to the sum of squares of

Wiener index of an ideal-based zero-divisor graph of commutative ring with unity

AKCE International Journal of Graphs and Combinatorics
The Wiener index of a connected graph G is [Formula: see text]. In this paper, we obtain the Wiener index of H-generalized join of graphs [Formula: see text]. As a consequence, we obtain some earlier known results in [Alaeiyan et al. in Aust. J.

The First Zagreb Index and the Narumi-Katayama Index of the Non-Commuting Graph on the Group U_{6n}

InPrime
This paper introduces a novel approach to computing the First Zagreb and Narumi–Katayama indices for non-commuting graphs associated with specific algebraic groups, specifically focusing on the group U_{6n}.
