On the null structure of bipartite graphs without cycles of length a multiple of 4
Daniel A. Jaume, Gonzalo Molina, Adrián Pastine
In this work we study the null space of bipartite graphs without cycles of length multiple of , and its relation to structural properties. We decompose them into two subgraphs:…

Maximum and minimum nullity of a tree degree sequence
Gonzalo Molina, Daniel A. Jaume
The nullity of a graph is the multiplicity of the eigenvalue zero in its adjacency spectrum. In this paper, we give a closed formula for the minimum and maximum nullity among trees…

On the structure of the fundamental subspaces of acyclic matrices with in the diagonal
Daniel A. Jaume, Adrián Pastine
A matrix is called acyclic if replacing the diagonal entries with , and the nonzero diagonal entries with , yields the adjacency matrix of a forest. In this paper we show tha…
