WebWe state Ramsey’s theorem for 1-hypergraphs (which is trivial) and for 2-hypergraphs (just graphs). The 2-hypergraph case, along with the a-hypergraph case, is due to Ramsey … Webhypergraph Ramsey numbers (k ≥ 3) is even weaker. Recall that rk(s,n) is the minimum N such that every red-blue coloring of the k-tuples of an N-element. Recent Developments in Extremal Combinatorics 2583 set contains a red set of size s or a blue set of size n. Erdo˝s, Hajnal, and Rado
