 * The following discussion is an archived debate of the proposed deletion of the article below. Please do not modify it. Subsequent comments should be made on the appropriate discussion page (such as the article's talk page or in a deletion review).  No further edits should be made to this page.

The result was redirect to Induced homomorphism. And merge to Wikiversity or Wikibooks, if anybody is interested.  Sandstein  18:20, 12 March 2016 (UTC)

Induced homomorphism (quotient group)

Fails WP:NOTTEXTBOOK. The article was previously deprodded by DanielConstantinMayer with this edit. GeoffreyT2000 (talk) 04:57, 18 February 2016 (UTC)


 * Comment: If DanielConstantinMayer was willing to work on this to make it more of an encyclopedia article and less of a textbook, then I think userfying could be an option here. Unfortunately, it looks like Daniel hasn't edited on Wikipedia since November 2015. Also, anything salvageable from this article may ultimately need to be merged into induced homomorphism. I am not familiar with this topic, so I will defer to more knowledgeable editors to determine whether merger is ultimately the best course of action. -- Notecardforfree (talk) 08:24, 18 February 2016 (UTC)


 * Comment The article is basically the appendix (section 7) of this paper by Daniel C Mayer. It would be a copyvio if it came from a different editor. As it is, this article is not close to the summary style of an encyclopedia article. The article would need a good bit of cutting and summarizing to make it a decent article. Induced homomorphism is a common enough concept in algebra that I think the topic is notable. Still thinking about what recommendation to make. --Mark viking (talk) 05:17, 19 February 2016 (UTC)
 * Do you know if there is any meaningful difference between Induced homomorphism (quotient group) and in general? I ask because I wonder if this topic deserves a standalone page (even if the current content needs to be WP:TNTed), or if the article for induced homomorphism is the more appropriate place to put this kind of information. Thanks in advance for your advice, -- Notecardforfree (talk) 05:52, 19 February 2016 (UTC)
 * An induced homomorphism is a type of functor, and as such, is a type of mapping that can apply to many different kinds of mathematical objects. This article is a particular application of the general idea to groups and quotient groups. There is in principle nothing wrong with having standalone articles on particular applications, because there may be implications in the particular case that go beyond the general idea. Hence the parent homomorphism is a broad concept article that begat articles on particular applications like group homomorphism, ring homomorphism, etc. That said, a well-summarized form of this article, along with the stubby Induced homomorphism (algebraic topology) and start class Induced homomorphism (fundamental group) could probably all me merged into a decent article on induced homomorphism. This article as it stands would be a fine contribution to Wikiversity or Wikibooks. In my opinion, transwiki would be preferable to WP:TNT. --Mark viking (talk) 13:23, 19 February 2016 (UTC)
 * That was an excellent explanation. I think your proposed course of action is a good idea for this article, and I am going to officially vote to transwiki the material in this article to Wikiversity or Wikibooks. After that is done, it may simply be best to redirect the title of the article to induced homomorphism. -- Notecardforfree (talk) 19:14, 19 February 2016 (UTC)

 * Transwiki to Wikiversity and redirect to induced homomorphism. See my reasoning above. The article could have a chance of being kept if it could be rewritten in encyclopedic summary style, but as it is, it is best to transwiki. No prejudice to the creation of a more encyclopedic article on the topic. --Mark viking (talk) 01:36, 5 March 2016 (UTC)
