References
[edit]Any references for the results stated on this page? For example, for the results that metrizable spaces are hereditarily collectionwise normal? Or the equivalence with hereditarily collectionwise normal? Yann Pequignot (talk) 20:56, 13 September 2023 (UTC)
- I added some easy justification. PatrickR2 (talk) 05:03, 14 September 2023 (UTC)
- Thanks, what you added for metrizable spaces is sufficient in my opinion. Any references for proving the equivalence between the various characterizations of hereditarily collectionwise normal? Yann Pequignot (talk) 19:27, 14 September 2023 (UTC)
Collectionwise normal implies collectionwise Hausdorff
[edit]@VictorAyabe You recently added a supposed reference for this result. But the reference does not show that result in any way. It does not even mention collectionwise Hausdorff anywhere. The result is trivial to check directly, so a reference is not really needed. But in any case, this incorrect reference must be removed.
I'll give you a chance to respond. If not hearing from you after a day or two, I'll remove it. Cheers. PatrickR2 (talk) 04:48, 8 August 2025 (UTC)
- Alright, thank you for your reply! I'll remove the reference right now. VictorAyabe (talk) 10:07, 8 August 2025 (UTC)
