Talk:Vietoris–Begle mapping theorem

Unclear: which homology?

"Note that as stated the theorem doesn't hold for homology theories like singular homology. "

so the question is: which is the correct homology (for the theorem to hold valid), if not the singular one? maybe cech homology? see https://encyclopediaofmath.org/wiki/Vietoris-Begle_theorem --93.34.148.90 (talk) 18:17, 31 October 2021 (UTC)
