Partitions of sets of finite sequences of positive integers

Carlos A. Di Prisco

Work in collaboration with Jimena Llopis and Stevo Todorcevic will be presented. The main result deals with partitions of collections of finite products of finite sets of positive integers, and is is stated as follows.

There is a function h: \omega^{< \omega} --> \omega such that for every sequence {m_i}_{i < \omega} of positive integers and every partition

c:
È
j < \omega

Õ
i <= j
h(m₀, ... , m_i) --> 2,

there is a sequence [H\vec]={H_i}_{i < \omega} with H_i subset or equal h(m₀, ... , m_i) and |H_i|=m_i such that {j in \omega: c is constant on \prod_{i < j}H_i} is infinite.
