Prod was applied, prod2 was applied. Removed by user without improvement. Not much information here. Does not appear to be notable for a single article. Is there a better place to redirect this? Is there anything that can be expanded? — Timneu22 · talk 16:36, 22 December 2010 (UTC)[reply]

Weak Delete I agree, too brief and could be applied elsewhere within its context. Warrior777 18:26, 22 December 2010 (UTC) — Preceding unsigned comment added by Warrior777 (talk • contribs)
Delete unless expanded, this is just a dictionary definition at the moment. Hairhorn (talk) 19:21, 22 December 2010 (UTC)[reply]

The nomination really should read, instead of "Removed by user without improvement" which is a completely erroneous description of events, "Removed by user after this improvement that directly addressed the concern raised". "No sources", said the proposed deletion rationale, only five lines above text that said "Source:". It's saddening to see a list of editors accruing in this discussion (a) who clearly don't understand what a stub is and how deletion policy applies to stubs, and (b) who clearly haven't even done a minimum of research to see whether sources exist (including not even observing the source cited, by the article's creator, in the article right before them, that they are supposed to be looking at). None of you even did the most basic step of putting the article title (let alone any other keywords) into a search engine, did you? Neither AFD nor Wikipedia need zero-effort rationales like this; New Pages Patrol certainly doesn't need people who bite the newcomers without doing their research. Please put the effort in. Put into actual action the procedures that are outlined on Project:New pages patrol, Project:Articles for deletion#Before nominating an article for deletion, Project:Guide to deletion#Nomination, and User:Uncle G/Wikipedia triage#What to do.

Comment - I've never seen an article like the current state. A one-sentence description with ten times as much information in "see also" and "external links"? — Timneu22 · talk 23:28, 22 December 2010 (UTC)[reply]
- Again you demonstrate that you aren't reading the article that is right in front of you. This article, as I write this, has no "see also" section and has no "external links" section. This article has a good verifiable definition, a supporting reference cited by the article's creator (that you just ignored outright), and sources cited listing further reading on the subject showing just some of what more there is to be said about it. This is what we call a stub. If you've never seen a stub before, then you haven't participated in the article development process anywhere near enough. If your reaction to stubs is, as here, to ignore the sources and nominate the article for deletion over and over again, biting a novice article writer in the process, then you are no help to Wikipedia. Your approach is entirely contrary to how articles develop, and have many times (over the past decade) developed, here. Our article on banana started as a one-line stub with a technical definition and a pointer to a source indicating scope for expansion. Articles start as stubs today just as they did in 2002.

Delete, possibly speedy. Without any evidence of what pseudoconvex and pseudoconcave might be, it has insufficient context to determine the meaning. However, some of the references might have adeqaute information to save it from {{db-context}}. — Arthur Rubin (talk) 01:14, 23 December 2010 (UTC)[reply]
- Tut tut! You've not read any of them, have you? The source that defines pseudoconvexity, that several of the others themselves cite for their definition, has been handed to you on a platter in the article that you are supposed to have read before commenting upon. Shame on you M. Rubin. You have made as little effort to read the article in front of you, and apply deletion policy properly to a stub with sources and a proper definition, as the four editors above. It is a proper definition, too, that accords with the sources. Valid stub, with a proper verifiable definition, the source for which was supplied by the article's creator, and with scope for expansion that is not only demonstrable but demonstrated: You know what, per policy, the answer you should have reached is. Uncle G (talk) 05:39, 23 December 2010 (UTC)[reply]
  - Speedy is no longer appropriate, but I doubt the concept is that notable. And it now has only a valid definition, and "references". Scope for expansion within Wikipedia guidelines has not been demonstrated, although I wouldn't be surprised if it could be done. Now it would be appropriate to userfy if deletion is supported. — Arthur Rubin (talk) 10:21, 23 December 2010 (UTC)[reply]
  - I don't have access to the references at the moment; as for some other articles, I'd like confirmation that all the articles about pseudolinear or pseudocovex functions were referring to the same concept. — Arthur Rubin (talk) 10:23, 23 December 2010 (UTC)[reply]
I propose to call the article pseudoconvex function. I am a wiki-beginner and don't have much time to deal with it. Hope someone can expand this article.
Rename to pseudoconvex function. The article pseudoconvex function currently redirects to plurisubharmonic function, which is incorrect (those characterize pseudoconvex domains). Our content on optimization and convex analysis is sorely lacking, so deletion is definitely inappropriate. However, the definition (as of the current revision) is incorrect.

Comment: The term does appear to be notable, see [1] for example. The article is basically just a definition though and my preference is to group similar concepts into a single article with redirects; better to have one decent small article than three stubs.--RDBury (talk) 17:28, 23 December 2010 (UTC)[reply]
Comment I've extended it beyond a mere definition. Maybe someone should add a comment on its application to mathematical economics. Michael Hardy (talk) 20:34, 23 December 2010 (UTC)[reply]
Keep The topic is clearly notable and so the article should be retained for improvement per our editing policy. Colonel Warden (talk) 00:00, 24 December 2010 (UTC)[reply]
Delete: unsubstantiated claims of notability (and ubiquitous boilerplate reference to WP:IMPERFECT) notwithstanding, this article is simply a set of mathematical definitions, making it directly analogous to WP:DICTDEF (except there probably isn't a Wikimath to transwiki it to).
