On some spectral properties of complex unit gain graph
Let ? = (G, ?) be a T-gain graph. In this note we show that ? has one positive and negative eigenvalues if and only if it is switching equivalent to a balanced complete bipartite graph or complete tripartite with special weights. In addition, we found some lower bounds for the energy of a T-gain graph.
