This points out another problem of pi-base, a lot of spaces from Counterexamples were defined in a way that's been very neglectful, and not a lot of them have been...
I haven't explained the exact reason why _Counterexamples_ is wrong, but the reason is basically that in their argument they use that the cardinal they are working with is a...
In literature Mysior plane refers to two different spaces, one of which is not Tychonoff. Not sure if this is a problem
I believe this space is not countably paracompact, but I don't know so I'll just leave that property for future PR I don't know if it's strongly zero-dimensional, I'll also...
I need someone to give me a source that any uncountable subset of $\mathbb{R}$ contains a two-sided condensation point. I.e. a point $x\in A$ such that for any $y <...
@yhx-12243 no, that only shows that there are condensation points
I've added the property but I still need to add a citation there
@yhx-12243 you can post there if you feel that way. I abstain from the rights to my proofs so feel free to copy those, or parts of them if you...
@prabau oh, thanks! This proof looks exactly like the one by @yhx-12243
@yhx-12243 to be clear, I won't post or answer a question, is what I meant in particular
