    • On the beta-number of forests with isomorphic components 

      Ichishima, R.; López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Oshima, Akito (2018)
      Article
      Accés obert
      The 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)| ...
    • Perfect (super) Edge-Magic Crowns 

      López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Prabu, M. (2017-01-06)
      Article
      Accés obert
      A 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'editorial
      The 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 ...

    • Rainbow eulerian multidigraphs and the product of cycles 

      López Masip, Susana Clara; Muntaner Batle, Francesc Antoni (2016-01-01)
      Article
      Accés obert
      An 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 ...
    • Super edge-magic models 

      López Masip, Susana Clara; Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2011-04-20)
      Article
      Accés obert
      In this paper, we generalize the concept of super edge-magic graph by introducing the new concept of super edge-magic models.
    • Vertex-transitive graphs that remain connected after failure of a vertex an its neighbors 

      Hamidoune, Yahya Ould; Lladó Sánchez, Ana M.; López Masip, Susana Clara (Wiley InterScience, 2010)
      Article
      Accés restringit per política de l'editorial
      A d-regular graph is said to be superconnected if any disconnecting subset with cardinality at most d is formed by the neighbors of some vertex. A superconnected graph that remains connected after the failure of a vertex ...
