Non-amenable factors
Hello. I just corrected the statement about hyperbolic groups and Ozawa which you noticed was not quite right and removed. The point about this paragraph (now a new section) is to explain progress to a general mathematical audience, so it should try to be non-technical if possible. What was surprising about Ozawa's result is that he extended Ge's results to a much wider class of groups, using quite different techniques. Perhaps the result of Voiculescu and Radulescu on the fundamental group of F∞ could be mentioned, as well as the open problem for Fn, possibly in the section on fundamental groups. It's probably best to avoid making wikilinks to pages that do not exist, unless you intend to create them. For example to wikilink to free group factors, make the link to the page on which they are discussed in detail, as I just did here. Regards, Mathsci 09:23, 8 October 2007 (UTC)
