Eigenvalues of complex unit gain graphs and gain regularity
Special MatricesA complex unit gain graph (or T{\mathbb{T}}-gain graph) Γ=(G,γ)\Gamma =\left(G,\gamma ) is a gain graph with gains in T{\mathbb{T}}, the multiplicative group of complex units.

Computing the determinant of a signed graph
Open MathematicsA signed graph is a simple graph in which every edge has a positive or negative sign. In this article, we employ several algebraic techniques to compute the determinant of a signed graph in terms of the spectrum of a vertex-deleted subgraph.

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