Combinatorics in the Art of the Twentieth Century
(2017)
Conference report
Open AccessThis paper is motivated by a question I asked myself: How can combinatorial structures be used in a work of art? Immediately, other questions arose: Whether there are artists that work or think combinatorially? If so, what ... -
Characterizing path-like trees from linear configurations
(2017)
Conference lecture
Open AccessAssume that we embed the path Pn as a subgraph of a 2-dimensional grid, namely, Pk¿Pl. Given such an embedding, we consider the ordered set of subpaths L1, L2,...,Lm which are maximal straight segments in the embedding, ... -

Locating-dominating partitions in graphs
(2016)
Conference report
Open AccessLet G = (V, E) be a connected graph of order n. Let ¿ = {S1, . . . , Sk} be a partition of V . Let r(u|¿) denote the vector of distances between a vertex v ¿ V and the elements of ¿, that is, r(v, ¿) = (d(v, S1), . . . ... -
On the spectra of Markov matrices for weighted Sierpinski graphs
(2016)
Conference report
Open AccessRelevant information from networked systems can be obtained by analyzing the spectra of matrices associated to their graph representations. In particular, the eigenvalues and eigenvectors of the Markov matrix and related ... -
Online graph coloring with advice and randomized adversary
(Springer, 2016)
Conference report
Restricted access - publisher's policyWe generalize the model of online computation with three players (algorithm, adversary and an oracle called advisor) by strength- ening the power of the adversary by randomization. In our generalized model, the advisor ... -
Genera Esfera: Interacting with a trackball mapped onto a sphere to explore generative visual worlds
(2016)
Conference report
Open AccessGenera Esfera is an interactive installation that allows the audience to interact and easily become a VJ (visual DJ) in a world of generative visuals. It is an animated and generative graphic environment with a music ... -
A geometric approach to dense Cayley digraphs of finite Abelian groups
(Elsevier, 2016)
Conference report
Open AccessWe give a method for constructing infinite families of dense (or eventually likely dense) Cayley digraphs of finite Abelian groups. The diameter of the digraphs is obtained by means of the related {\em minimum distance ... -

Conference lecture
Restricted access - publisher's policyEl presente trabajo describe la implementación de una aplicación informática como recurso docente, diseñada como plataforma para la elaboración, utilización y corrección de controles formativos y exámenes de evaluación. ... -
Counting configuration–free sets in groups
(2015)
Conference lecture
Restricted access - publisher's policyWe present a unified framework to asymptotically count the number of sets, with a given cardinality, free of certain configurations. This is done by combining the hypergraph containers methodology joint with arithmetic ...
