From Wheel to Jahangir graphs: spectra and energy under structured edge deletion
Diego Bravo, Florencia Cubría, Annabella Zapattini
The energy of a graph, introduced by Gutman, is defined as the sum of the absolute values of the eigenvalues of its adjacency matrix. In this work we study how the energy of the Wh…
Some families of digraphs determined by the complementarity spectrum
Diego Bravo, Florencia Cubría, Marcelo Fiori +1
We examine the capacity of the complementarity spectrum to distinguish non-isomorphic digraphs. We focus on the seven families with exactly three complementarity eigenvalues. Our f…
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…
Generalised Igusa-Todorov functions and Lat-Igusa-Todorov algebras
Diego Bravo, Marcelo Lanzilotta, Octavio Mendoza +1
In this paper we study a generalisation of the Igusa-Todorov functions which gives rise to a vast class of algebras satisfying the finitistic dimension conjecture. This class of al…
Idempotent reduction for the finitistic dimension conjecture
Diego Bravo, Charles Paquette
In this note, we prove that if is an Artin algebra with a simple module of finite projective dimension, then the finiteness of the finitistic dimension of implies that…
Pullback diagrams, syzygy finite classes and Igusa-Todorov algebras
Diego Bravo, Marcelo Lanzilotta, Octavio Mendoza
For an abelian category , we define the category PEx() of pullback diagrams of short exact sequences in , as a subcategory of the functor cat…
