Characterization of digraphs with three complementarity eigenvalues
Diego Bravo, Florencia Cubría, Marcelo Fiori +1
Given a digraph D, the complementarity spectrum of the digraph is defined as the set of complementarity eigenvalues of its adjacency matrix. This complementarity spectrum has been…
Complementarity spectrum of digraphs
Diego Bravo, Florencia Cubría, Marcelo Fiori +1
In this paper we study the complementarity spectrum of digraphs, with special attention to the problem of digraph characterization through this complementarity spectrum. That is, w…
On spectral properties for graph matching and graph isomorphism problems
Marcelo Fiori, Guillermo Sapiro
Problems related to graph matching and isomorphisms are very important both from a theoretical and practical perspective, with applications ranging from image and video analysis to…
