On equivalences of polarized partition relations
摘要
The paper deals with two notions: polarized partition relations and the product of generalized strong sequences. Strong sequences were introduced by Efimov in 1965 as a useful tool for proving famous theorems in dyadic spaces, i.e. continuous image of the Cantor cube. In this paper we introduce the notion of the product of generalized strong sequences and give a pure combinatorial proof that the existence of the product of generalized strong sequences is equivalent to polarized partition relations.
