The Laplacian spectral radii ordering of unbalanced signed bicyclic graphs
In this paper,the distribution law of the Laplacian eigenvalues from the first to the sixth of the unbalanced signed bicyclic graphs is studied,some inaccuracies of the existing conclusions are corrected,the existing results are generalized,and the legend of the extreme value is given.
