This mathematical article is based on four recent articles (2015) by the same author, published in the same journal. The journal is not a reliable source, as it has not mathematics in its topic, and is not reviewed by Zentralblatt MATH nor by MathSciNet. A Scholar Google search shows that the title of the article is a neologism that appear only in these four articles, and that these articles are not cited by other authors. Thus the topic is non-notable WP:OR. D.Lazard (talk) 09:14, 22 January 2017 (UTC)[reply]

Keep – Searching the term gives these three links: [1]; [2]; [3]; from an unrelated website. There is also this, this, and a .edu site here, here and here. The sequence also appears in the OEIS and it cannot be OR because the article is referenced. How do you define notability of a mathematical concept? Also, why did you put a COI tag on the page?

Comment – There is a paper in the IJST, which is peer reviewed (here), so there is fact a reliable source in the article. Laurdecl ^talk 10:32, 22 January 2017 (UTC)[reply]

This confirms that this is WP:OR: Except for the last comment, all non-anonymous links that are provided by Laurdecl (the author of the WP article) are authored by the same author, and either not published or published in the same journal. About the question of notability, a common criteria is that a mathematical concept cannot been notable, if it has never been mentioned in an article reviewed by MathSciNet or Zentralblatt. The reference provided in the last comment is by the same author, in a journal which is not reviewed by MathSciNet nor Zentralblatt (source: the site of the journal itself).
