2007 seminar talk: In and around the Ramsey property
Talk held by Philip Welch (University of Bristol) at the KGRC seminar on 2007-12-13.
Abstract
Recent work on the Mutual Stationarity property has prompted looking at some finite sequence "mutual stationarity" of subsets of omega_1 and omega_2. We discuss some joint work with I. Sharpe on this, related also to mild strengthenings of the Chang Property; some further topics in the Jonsson/Ramsey hierarchy may be mentioned if time permits.
