Question 1. Let $\kappa<\lambda$ are uncountable regular cardinal. For any coloring $c: \kappa\times \lambda \rightarrow \omega$, are there $A\in [\kappa]^\kappa$ and $B\in [\lambda]^\lambda$ such that $c(A\times B)$ is constant?
Question 2. If the answer is no. Is it possible add some condition to make the proposition hold?
PS. I think this kind of results should be know, if possible, can someone provide reference to me, I didn't read book about this topic.
