Orphaned redundant disambiguation page. All math uses are mentioned in the broad concept article pullback, and the only unrelated one can be added as a hatnote. Nowak Kowalski (talk) 15:06, 13 October 2018 (UTC)[reply]

• Delete per nom. The main page performs the same navigational function as this page. Clarityfiend (talk) 08:02, 16 October 2018 (UTC)[reply]

• Addendum. I found a "pull-back", but I've added that to the existing hatnote in the main article. Clarityfiend (talk) 08:07, 16 October 2018 (UTC)[reply]

• Keep - there are several articles with wikilinks under this disambiguation, so the disambiguation is serving a purpose. Vorbee (talk) 15:48, 19 October 2018 (UTC)[reply]

• Comment. I've moved the partial matches to See also, leaving just the mathematical entries (which are already listed in the main page). If this page is kept, rename Pullback (disambiguation) since there are no "pull back"s. Clarityfiend (talk) 05:24, 21 October 2018 (UTC)[reply]

• Keep. It's a bog standard disambiguation page. Szzuk (talk) 18:48, 20 October 2018 (UTC)[reply]

• Rename to Pullback, overwriting the article there now. It's inappropriate to have a broad-concept article there, as it's not a broad concept, but several concepts with the same name, none of which are particularly primary, so a dab page at "Pullback" is appropriate. –Deacon Vorbis (carbon • videos) 17:53, 23 October 2018 (UTC)[reply]
• Delete, Pullback was formerly the disambiguation page but it appears ip editors changed it into an article that describes unrelated mathematical concepts. We need to delete this and return pullback to its proper usage. Szzuk (talk) 18:30, 23 October 2018 (UTC)[reply]

• Per WP:BOLD I've just turned Pullback back into a disambiguation. I'm not bothered enough to revert if anyone is unhappy. Szzuk (talk) 18:44, 23 October 2018 (UTC)[reply]
• Reverted your bold edit. The article as it stands may be unreadable to non-mathematicians, but these are really cases of the same general concept — see for example [1]. (This was not obvious to me as someone who knows some category theory, but next to none differential geometry — this article could use a rewrite.) Nowak Kowalski (talk) 20:31, 23 October 2018 (UTC)[reply]

The mathematical concepts probably do have some inherent value so could possibly merge elsewhere but I don't think such a broad term as pullback should be used for this niche so I was essentially agreeing with Deacon Vorbis, anyway I will see what others think. Szzuk (talk) 20:46, 23 October 2018 (UTC)[reply]

@Nowak Kowalski, how about - 1) move Pullback to Pullback (mathematics), 2) revert Pullback to the dab page for the generic term 3) delete Pull back (disambiguation). Szzuk (talk) 07:34, 24 October 2018 (UTC)[reply]

• Keep pullback at its current title either as a set index article or actual normal article (not dab), because this is about related concepts rather than about disambiguating unrelated concepts with similar names. The relation between these related concepts is notable mathematically (recognizing this kind of commonality is exactly what category theory is for and there should be plenty of book sources for it). But delete Pull back (disambiguation) and do not make a separate dab article because all but one of the entries on the current dab fork are more or less the same mathematical concept (the exception is pullback motor) so having a separate dab would fail WP:2DABS. —David Eppstein (talk) 05:20, 26 October 2018 (UTC)[reply]

• Comment, there is only one keep vote for this article with most of the discussion about how to best use the pullback name space. Szzuk (talk) 17:14, 3 November 2018 (UTC)[reply]
• Keep. Valid DAB page even with current entries. There's also entries that are not there like Withdrawal (military) and others. ---- Patar knight - ^chat/_{contributions} 03:26, 4 November 2018 (UTC)[reply]
