• Anti-Ramsey Number of Matchings in Hypergraphs 

      Özkahya, Lale; Young, Michael (Elsevier Science Bv, 2013)
      A k-matching in a hypergraph is a set of k edges such that no two of these edges intersect. The anti-Ramsey number of a k-matching in a complete s-uniform hypergraph H on n vertices, denoted by ar(n, s, k), is the smallest ...
