Extract

Problems about partitions of cartesian products are common in mathematics. For example, in finite and infinite combinatorics, they keep emerging in Ramsay theory, where one seeks to show that, if a product is partitioned into finitely many parts, one part at least must contain a subset of a certain specified kind. In the transition from finite to infinite products, one usually imposes restrictions of a topological nature on the partition, in order to obtain theorems analogous to those which are valid in the finite case. (See, e.g., [G-P], [Si], [E].)
