| Mar 17, 2014 at 1:35 | comment | added | Noah Schweber | That's a good point - although that definition is (?) $\Delta^1_2$, whereas if something like Miller's Borel strictly Dedekind finite set lacked FPP, then we'd have a definition of much lower complexity, and probably(?) close to minimal possible complexity - at least, among topological spaces whose underlying set is a set of reals. | |
