All connected generalized line graphs whose second largest eigenvalue does not exceed 1 are characterized. Besides, all minimal generalized line graphs with second largest eigenvalue greater than 1 are determined.
Classification : 05C50
Keywords: Generalized line graphs, minimal generalized line graphs, second largest eigenvalue of graph
