    • Graphs admitting antimagic labeling for arbitrary sets of positive integers 
      Matamala Vásquez, Martín; Zamora, José (Elsevier, 2017)
      A connected graph G=(V,E) with m edges is called universal antimagic if for each set B of m positive integers there is an bijective function f:E→B such that the function f˜:V→N defined at each vertex v as the sum of all ...
    • Graphs admitting antimagic labeling for arbitrary sets of positive numbers 
      Matamala Vásquez, Martín; Zamora, José (Elsevier, 2020)
      Hartsfield and Ringel in 1990 conjectured that any connected graph with q >= 2 edges has an edge labeling f with labels in the set {1,..., q}, such that for every two distinct vertices u and v, f(u) not equal= f(v), where ...
