    • FORCING LARGE COMPLETE (TOPOLOGICAL) MINORS IN INFINITE GRAPHS∗ 
      Stein, Maya; Zamora, José (Society for Industrial and Applied Mathematics, 2013)
      It is well known that in finite graphs, large complete minors/topological minors can be forced by assuming a large average degree. Our aim is to extend this fact to infinite graphs. For this, we generalize the notion of ...
    • 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 ...
    • A new family of expansive graphs 
      Matamala Vásquez, Martín; Zamora, José (ELSEVIER SCIENCE BV, 2008-04-01)
      An affine graph is a pair (G, ) where G is a graph and is an automorphism assigning to each vertex of G one of its neighbors. On one hand, we obtain a structural decomposition of any affine graph (G, ) in terms of the ...
