Abstract
Let denote the complete -uniform hypergraph on vertices and the -uniform hypergraph on vertices consisting of all edges incident to a given vertex. Whereas many hypergraph Ramsey numbers grow either at most polynomially or at least exponentially, we show that the off-diagonal Ramsey number exhibits an unusual intermediate growth rate, namely, for some positive constants and . The proof of these bounds brings in a novel Ramsey problem on grid graphs which may be of independent interest: what is the minimum such that any -edge-coloring of the Cartesian product contains either a red rectangle or a blue ?
