dc.description.abstract | A graph is integral if the spectrum (of its adjacency matrix) consists entirely of integers. The problem of determining all non-regular bipartite integral graphs with maximum degree four which do not have ±1 as eigenvalues was posed in K.T. Balińska, S.K. Simić, K.T. Zwierzyński: Which nonregular bipartite integral graphs with maximum degree four do not have ±1 as eigenvalues? DiscreteMath., 286 (2004), 15-25. Here we revisit this problem, and provide its complete solution using mostly the theoretical arguments. | en |
