    • Partial characterization of graphs having a single large Laplacian eigenvalue 

      Allem, Luiz Emílio; Cafure, Antonio Artemio; Dratman, Ezequiel; Grippo, Luciano Norberto; Safe, Martín Darío; Trevisan, Vilmar (2018) [Journal article]
      The parameter (G) of a graph G stands for the number of Laplacian eigenvalues greater than or equal to the average degree of G. In this work, we address the problem of characterizing those graphs G having (G) = 1. Our ...
