As noted at the WikiProject Mathematics discussion page, this is original research. All of the discussions on the article's Talk page, going back to 2011, are about how it's not a real topic. A prod that was endorsed was then removed. XOR'easter (talk) 20:12, 12 December 2023 (UTC)[reply]

Delete. I was unsure before, but the WT:WPM discussion convinced me that this is original research. No reliable sources for this topic have been uncovered. —David Eppstein (talk) 20:35, 12 December 2023 (UTC)[reply]
Delete The article's talk page has been preserved at the talk page of this AfD. Aside from being OR, it is entirely a series of DICDEFs. –LaundryPizza03 (d c̄) 20:39, 12 December 2023 (UTC)[reply]
Delete A search of academic literature for "External magma" turns up sources about magma. "External semiring" turns up a couple of results about universal joints. "External semigroup" and "external monoid" turn up only a few results each. "Left external binary operation" turns up nothing at all. It look like this may be a couple authors' personal nomenclature which has not been adopted by anyone else yet. –jacobolus (t) 21:51, 12 December 2023 (UTC)[reply]

Delete per nom, WP:OR, only one source used in the intro. Frigyes06 (talk) 22:13, 12 December 2023 (UTC)[reply]
Addendum: A passage added by the page creator and since removed makes clear that this article was trying to make fetch happen: It could be argued that we already have terms for the concepts described here, like dynamical systems, group actions, modules, and vector spaces. However, there is still no other terminology available for an external monoid for which this terminology gives us a concise expression. Above all else, this is a reason this term should be of use in the mathematical community. XOR'easter (talk) 23:59, 12 December 2023 (UTC)[reply]

Delete per nom and @XOR'easter - The concept of "external" as described lacks clear definition and context within established mathematical literature. The provided references do not appear to be from reliable, secondary sources that are independent of the subject, as required by Wikipedia's general notability guideline WP:GNG. As sstated above, the article seems to contain original research WP:OR and fails to cite significant coverage in reliable sources that are independent of the subject WP:SIGCOV. Without verifiable and reliable sources, the term does not meet Wikipedia's notability standards for inclusion.

Delete: I found two primary source mentions of the term "external semiring", and one of them was about antenna design. I applaud the author's attempt to coin a useful new term, but WP isn't the place to do that. Owen× ☎ 14:35, 13 December 2023 (UTC)[reply]
Delete per nom. This is pure original terminology from the author, not attested anywhere in the literature. PatrickR2 (talk) 03:31, 14 December 2023 (UTC)[reply]
Comment If this is deleted, some of the material should be kept, in other articles. Including some of the lists of examples. Michael Hardy (talk) 04:28, 18 December 2023 (UTC)[reply]
