Antimagic labelings of caterpillars
(2019-04-15)
Article
Accés obertA 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
(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 edge-magic graphs
(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 ...
