Resumen de New bounds on the distance Laplacian and distance signless Laplacian spectral radii
Roberto Carlos Díaz, Ana Julio, Óscar Rojo
Let G be a simple undirected connected graph. In this paper, new upper bounds on the distance Laplacian spectral radius of G are obtained. Moreover, new lower and upper bounds for the distance signless Laplacian spectral radius of G are derived. Some of the above mentioned bounds are sharp and the graphs attaining the corresponding bound are characterized. Several illustrative examples are included.
