Magic coverings and the Kronecker product
López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2014-11-01)
Article
Accés restringit per política de l'editorialIn this paper we study a relationship existing among (super) magic coverings and the well known Kronecker product of matrices. We also introduce the concept of Z(n)-property for digraphs in order to study this relation ... -

Accés obertIn this paper we study a relationship existing among (super) magic coverings and the well known Kronecker product of matrices. We also introduce the concept of Zn–property for digraphs in order to study this relation ... -
On the beta-number of forests with isomorphic components
Ichishima, R.; López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Oshima, Akito (2018)
Article
Accés obertThe beta-number, ß (G), of a graph G is defined to be either the smallest positive integer n for which there exists an injective function f : V (G) ¿ {0, 1, . . . , n} such that each uv ¿ E (G) is labeled |f (u) - f (v)| ... -
On the structure of path-like trees
Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2007)
Article
Accés obertWe study the structure of path-like trees. In order to do this, we introduce a set of trees that we call expandable trees. In this paper we also generalize the concept of path-like trees and we call such generalization ... -
Perfect (super) Edge-Magic Crowns
López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Prabu, M. (2017-01-06)
Article
Accés obertA graph G is called edge-magic if there is a bijective function f from the set of vertices and edges to the set {1,2,…,|V(G)|+|E(G)|} such that the sum f(x)+f(xy)+f(y) for any xy in E(G) is constant. Such a function is ... -
Perfect edge-magic graphs
López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2014-01-01)
Article
Accés restringit per política de l'editorialThe study of the possible valences for edge-magic labelings of graphs has motivated us to introduce the concept of perfect edge-magic graphs. Intuitively speaking, an edge-magic graph is perfect edge-magic if all possible ... -
Problemas abiertos sobre etiquetamientos super edge-magic y temas relacionados
López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2010)
Text en actes de congrés
Accés obertEl tema de los etiquetamientos de grafos ha experimentado un fuerte impulso en los últimos 40 años, muestra de ello son los dos libros dedicados en exclusiva a ellos, un completísimo artículo ”survey” y más de 1000 ... -
Queen Labelings
Bloom, Gary; Lampis, Michael; Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2008)
Article
Accés obertWe introduce and investigate the concept of Queen labeling a digraph and its connection to the well-known n-queens problem. In the general case we obtain an upper bound on the size of a queen graph and show that it is ... -
Rainbow eulerian multidigraphs and the product of cycles
López Masip, Susana Clara; Muntaner Batle, Francesc Antoni (2016-01-01)
Article
Accés obertAn arc colored eulerian multidigraph with l colors is rainbow eulerian if there is an eulerian circuit in which a sequence of l colors repeats. The digraph product that refers the title was introduced by Figueroa-Centeno ... -
Strong labelings of linear forests
Baca, Martin; Lin, Yu Qing; Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2009-11-15)
Article
Accés obertA (p, q)-graph G is called super edge-magic if there exists a bijective function f : V (G) ∪ E(G) → {1, 2, . . . , p+q} such that f(u)+f(v)+f(uv) is a constant for each uv ∈ E(G) and f(V (G)) = {1, 2, . . . , p}. In ... -
Super edge-magic models
López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2011-04-20)
Article
Accés obertIn this paper, we generalize the concept of super edge-magic graph by introducing the new concept of super edge-magic models.
