Jan 3, 2018 at 12:11 comment added Martin Sleziak The link in the post is now dead. I suppose it is supposed to be link to the paper Neil Hindman: Algebra in the Stone-Cech compactification and its applications to Ramsey theory, Scientiae Mathematicae Japonicae 62 (2005), 321-329. Here is Wayback Machine version and als a new link - nhindman.us/research/jams.pdf
