Computing the determinant of a signed graph

Open Mathematics
A 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

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 ...
