| Feb 7, 2011 at 23:33 | comment | added | Dan Ramras | I don't think Baum was suggesting that every non-exact group with a nice classifying space would give a counterexample. He just indicated that this is a good place to look for counterexamples. | |
| Feb 6, 2011 at 23:55 | comment | added | user6976 | @Dan: thanks! But existence of a compact aspherical manifold with non-exact fundamental group would not automatically disprove the conjecture? | |
| Feb 6, 2011 at 21:34 | comment | added | Dan Ramras | Paul Baum gave a series of lectures on BC at Vanderbilt in Spring 2008 (I believe you were on sabbatical, Mark). I recall him saying that he expected the original BC conjecture to be true for all exact groups, but that he didn't know of a counterexample to original conjecture. But I guess his point was that one should study non-exact groups. | |

| Jan 31, 2011 at 22:55 | comment | added | user9072 | Vincent Lafforgue has (also) written some expository articles on Baum--Connes, one of them fairly recent. (Available on his website math.jussieu.fr/~vlafforg) I appologize in advance, if this remark is to general to be useful; I just happended to remember this fact, but am not well-informed on this subject. | |
| Jan 31, 2011 at 22:49 | comment | added | Theo Buehler | I'm sure a lot has happened in the last 6 years, but Wolfgang Lück has a rather extensive survey in the Handbook of -theory (containing a chapter about the status of the conjectures). It focuses more on the positive aspects, though. You can find it at arxiv.org/abs/math/0402405 | |
