Four-cycled graphs with topological applications
(Birkhauser Verlag AG, 2012-03)We call a simple graph G a 4-cycled graph if either it has no edges or every edge of it is contained in an induced 4-cycle of G. Our interest on 4-cycled graphs is motivated by the fact that their clique complexes play an ... -
Some notes on spectra of cographs
(Charles Babbage Res Ctr, 2011-07)A cograph is a P-4-free graph. We first give a short proof of the fact that 0 (-1) belongs to the spectrum of a connected cograph (with at least two vertices) if and only if it contains duplicate (resp. coduplicate) vertices. ...
