Structural and Spectral Properties of Strictly Interval Graphs
Claudia Justel, Lilian Markenzon
In this paper we deal with a subclass of chordal graphs, which are simultaneously strictly chordal and interval, the strictly interval graphs. We present a new characterization of…

Integer Laplacian eigenvalues of strictly chordal graphs
Nair Abreu, Claudia Marcela Justel, Lilian Markenzon
In this paper, we establish the relation between classic invariants of graphs and their integer Laplacian eigenvalues, focusing on a subclass of chordal graphs, the strictly chorda…

Integer Laplacian Eigenvalues of Chordal Graphs
Nair Maria Maia de Abreu, Claudia Marcela Justel, Lilian Markenzon
In this paper, structural properties of chordal graphs are analysed, in order to establish a relationship between these structures and integer Laplacian eigenvalues. We present the…
