| Dec 21, 2022 at 11:33 | comment | added | FShrike | @IvanDiLiberti I regret to inform you I'm no longer sure if that is even true. A user on MSE commented, under my linked question, that we could make it work. For a time, I thought I'd figured it out, but I hadn't... | |

| Dec 21, 2022 at 9:26 | comment | added | FShrike | @IvanDiLiberti It is surprising and possibly even false. But if we further assume the existence of at least one point in $A_0$ that makes it a well-pointed space, then we can have the result. | |
| Dec 21, 2022 at 9:23 | comment | added | FShrike | @YTS I asked about how to amend this, on MSE here. With two sets of slightly stronger hypotheses, we can make it work, and that’s just so far. Maybe someone will find a way to make this proof always work | |
| Apr 24, 2019 at 14:26 | comment | added | YTS | Why the map $f$ reach just one point when $f_1$? It seems like in principle is just a sequence of points $x_n=\alpha_n(1)\circ \cdots \alpha_1(1)$ | |
