On rainbow-free colourings of uniform hypergraphs
We study rainbow-free colourings of k-uniform hypergraphs; that is, colourings that use k colours but with the property that no hyperedge attains all colours. We show that p⁎ = (k−1)(lnn)/n is the threshold function for the existence of a rainbow-free colouring in a random k-uniform hypergraph....
