edited the Google Books link (removed the redundant stuff)

| Mar 13, 2017 at 12:28 | comment | added | Asaf Karagila♦ | Now it states that Zermelo with Choice is false, and that a counterexample would be to either the Axiom of Choice, or something related to Power Set (and Choice, I guess)... :-P | |
| Jan 23, 2017 at 20:08 | comment | added | DKal | It may be also worth to mention that Adiprasito and Benedetti showed that for any contractible complex $C$ there is an $n\geq 0$ such that $C\times I^n$ is collapsible. See arxiv.org/pdf/1202.6606v3.pdf. | |
| Jan 23, 2017 at 17:21 | comment | added | DKal | @GilKalai, yes, for dimension $\geq 3$ it seems to have been shown in the 1977 paper "Whitehead torsion, group extensions, and Zeeman's conjecture in high dimensions" by M. Cohen. (here's the link to the paper: sciencedirect.com/science/article/pii/0040938377900313) | |
| Jan 23, 2017 at 11:50 | comment | added | Gil Kalai | If $K$ is higher dimensional (say, 3-dimensional) is the srarement of Zeeman's conjecture known to be false? | |
| Jan 23, 2017 at 9:00 | comment | added | DKal | @GerryMyerson, changed to AC. This also agrees with Matveev's use in the given quote. | |

Changed ACC to AC, as was implicitly suggested in one of the comments
|
| Jan 22, 2017 at 11:52 | comment | added | Gerry Myerson | "ACC" is overloaded – Andrews-Curtis conjecture, Ascending Chain Condition, Axiom of Countable Choice. | |
| Jan 22, 2017 at 10:45 | comment | added | Gil Kalai | Zeeman's conjecture assert that for a 2-dimensional contractible complex $K$, $K \times I$ is collapsible. ($I$ is the unit interval.) | |
