On a problem of Henning and Yeo about the transversal number of uniform linear systems whose 2-packing number is fixed

Carlos A. Alfaro, Adrián Vázquez-Ávila

A linear system is a pair $(P, L)$ where $L$ is a family of subsets on a ground finite set $P$ such that $∣ l \cap l^{'} ∣ \leq 1$ , for every $l,l^\prime \in \mat…

Digraphs with at most one trivial critical ideal

Carlos A. Alfaro, Carlos E. Valencia, Adrián Vázquez-Ávila

Critical ideals generalize the critical group, Smith group and the characteristic polynomials of the adjacency and Laplacian matrices of a graph. We give a complete characterizatio…

On line colorings of finite projective spaces

Gabriela Araujo-Pardo, György Kiss, Christian Rubio-Montiel +1

In this paper, we prove lower and upper bounds on the achromatic and the pseudoachromatic indices of the $n$ -dimensional finite projective space of order $q$ .
