On the eigenvalues of complete bipartite signed graphs
On the eigenvalues of complete bipartite signed graphs
Let Γ = (G, σ) be a signed graph, where σ is the sign function on the edges of G. The adjacency matrix of Γ is defined canonically. Let (Kp, q, σ), p ≤ q, be a complete bipartite signed graph with bipartition (Up, Vq), where Up = {u1, u2, …
