ON THREE CONJECTURES INVOLVINGTHE SIGNLESS LAPLACIANSPECTRAL RADIUS OF GRAPHS

摘要

We study the signless Laplacian spectral radius of graphs andprove three conjectures of Cvetkovic, Rowlinson, and Simid [Eigenvalue boundsfor the signless Laplacian, Publ. Inst. Math., Nouv. Ser. 81(95) (2007),11-27].
