The $p$ -spectral radius of the Laplacian

Elizandro Max Borba, Sebastian Richter, Eliseu Fritscher +1

The $p$ -spectral radius of a graph $G = (V, E)$ with adjacency matrix $A$ is defined as $λ^{(p)} (G) = max {x^{T} A x : ∥ x ∥_{p} = 1}$ . This parameter shows remarkable connections with grap…

Loopy, Hankel, and Combinatorially Skew-Hankel Tournaments

Richard A. Brualdi, Eliseu Fritscher

We investigate tournaments with a specified score vector having additional structure: loopy tournaments in which loops are allowed, Hankel tournaments which are tournaments symmetr…

Unicyclic Graphs with equal Laplacian Energy

Eliseu Fritscher, Carlos Hoppen, Vilmar Trevisan

We introduce a new operation on a class of graphs with the property that the Laplacian eigenvalues of the input and output graphs are related. Based on this operation, we obtain a…

Characterizing Trees with Large Laplacian Energy

Eliseu Fritscher, Carlos Hoppen, Israel Rocha +1

We investigate the problem of ordering trees according to their Laplacian energy. More precisely, given a positive integer $n$ , we find a class of cardinality approximately $\sqrt{…
