The Hales-Jewett Theorem

Ujkan Sulejmani, Manuel Eberl and Katharina Kreuzer

Abstract

This article is a formalisation of a proof of the Hales--Jewett theorem
presented in the textbook Ramsey Theory by Graham et al.

The Hales--Jewett theorem is a result in Ramsey Theory which states that, for
any non-negative integers r
and t, there exists a minimal dimension N, such that any r-coloured
N'-dimensional cube over t elements (with N' >= N) contains a monochromatic
line. This theorem generalises Van der Waerden's Theorem, which has already been
formalised in another AFP entry.
