Fiedler vector analysis for particular cases of connected graphs
Daniel Felisberto Traciná Filho, Claudia Marcela Justel
In this paper, some subclasses of block graphs are considered in order to analyze Fiedler vector of its members. Two families of block graphs with cliques of fixed size, the block-…

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…
