Abstract

We study the probability threshold for the property of strong colorability with a given number of colors of a random \(k\)-uniform hypergraph in the binomial model \(H(n,k,p)\). A vertex coloring of a hypergraph is said to be strong if any edge does not have two vertices of the same color under it. The problem of finding a sharp probability threshold for the existence of a strong coloring with q colors for \(H(n,k,p)\) is studied. By using the second moment method, we obtain fairly tight bounds for this quantity, provided that q is large enough in comparison with k.
