Applications of rational difference equations to spectral graph theory: expanded version
Elismar R. Oliveira, Vilmar Trevisan
We study a general class of recurrence relations that appear in the application of a matrix diagonalization procedure. We find general closed formula and determine analytical prope…

Spectral ordering and 2-switch transformations
Elismar R. Oliveira, Victor N. Schvöllner, Vilmar Trevisan
We address the problem of ordering trees with the same degree sequence by their spectral radii. To achieve that, we consider 2-switch transformations which preserve the degree sequ…
