      A k-antimagic labeling of a graph G is an injection from E(G) to {1,2, ..., |E(G)|+k} such that all vertex sums are pairwise distinct, where the vertex sum at vertex u is the sum of the labels assigned to edges incident ...

    • On the structure of path-like trees 

      Muntaner Batle, Francesc Antoni; Rius Font, Miquel (2007)
      Article
      Accés obert
      We 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 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 ...
