Request for edit summary

When editing an article on Wikipedia there is a small field labelled "Edit summary" under the main edit-box. It looks like this:

The text written here will appear on the Recent changes page, in the page revision history, on the diff page, and in the watchlists of users who are watching that article. See m:Help:Edit summary for full information on this feature.

When you leave the edit summary blank, some of your edits could be mistaken for vandalism and may be reverted, so please always briefly summarize your edits, especially when you are making subtle but important changes, like changing dates or numbers. Thank you.

References for edits to Bessel functions

Please include references for the identities you are adding to Bessel function, or they may be removed. (See WP:CITE).

Also, you need to define your symbols. For example, what is $L_{k}^{(\alpha )}$?

Binomial coefficient

Hi, the edit you just made to binomial coefficient has an undefined s. McKay (talk) 12:19, 9 June 2009 (UTC)

I have no idea what you are talking about when you say that I "delete a lot of significant edits on various entries." As for not "[deleting] statements simply because you do not understand them", it is perfectly acceptable to delete nonsensical statements from articles. Here is the nonsense at issue confluent hypergeometric function:

Moreover,

$U(a,b,z)=z^{-a}\cdot \,_{2}F_{0}\left(a,1+a-b;\,;-{\frac {1}{z}}\right)$ ,

where $_{2}F_{0}(\cdot ,\cdot ;;z)$ is a generalized hypergeometric function, which converges nowhere but exists as a formal power series in z and solves the initial differential equation.

The right hand side is clearly not a "formal power series", nor can it exist as a formal power series, nor is the equality of the left and right-hand sides "as formal power series" well-defined here. So, before inserting again, please take a moment to consider carefully the meaning of the symbols involved. What, for instance, does "=" mean here? Sławomir Biały (talk) 13:43, 21 July 2009 (UTC)

Perhaps by the above you mean instead that

$U(a,b,z)\sim z^{-a}\cdot \,_{2}F_{0}\left(a,1+a-b;\,;-{\frac {1}{z}}\right)$

as an asymptotic series as z → 0 in the right half-plane? If so, the article should say this rather than expecting that readers will understand that from what is written above. Sławomir Biały (talk) 13:51, 21 July 2009 (UTC)

Your reference to Abramowitz and Stegun is mistaken. They do not mention this. As for the Weisstein, I challenge the reliability of that source. Sławomir Biały (talk) 14:37, 21 July 2009 (UTC)

You correctly assert that "=" is well-defined for formal power series, but totally missed the point. Please explain precisely what the meaning of the "=" in an expression of the form (an analytic function) = (a divergent formal power series in z) is. This is, of course, accepting that the right-hand side of the formula above is a formal power series in z, as you are so insistent. More properly, apart from the initial factor of z^−a, it is a formal power series in 1/z. Sławomir Biały (talk) 14:55, 21 July 2009 (UTC)

I went and looked this up in another book on special functions. Contrary to your continued assertion that this is a "formal power series" identity, a fact which you have yet to explain compellingly, it is rather an identity at the level of asymptotic series as I have continually suggested. In the future, it might behoove you to understand the difference between these two things. Sławomir Biały (talk) 15:34, 21 July 2009 (UTC)

Cite your sources!

You need to cite sources when you add identities and other maths information, e.g. your recent edits to Bessel function. It doesn't matter whether you know they are correct, the reader needs to be able to look up the source of the information in order to verify it or find more information. See WP:CITE and WP:V -- these are the fundamental principles of Wikipedia.

If you don't do this, your edits may be reverted. — Steven G. Johnson (talk) 16:18, 14 August 2009 (UTC)

You continue to add unreferenced information, which I am forced to revert! You must include references, or you are just wasting everyone's time. — Steven G. Johnson (talk) 16:25, 10 September 2009 (UTC)

Exponential Error

Hi I'm a math student and i'm interested in the error of the limit-expression of the exponential function. I would like to ask: Can you prove this? or give some page where is the proof? (You wrote this at Exponential function) ->

$\left(1+{\frac {x}{n}}\right)^{n}=e^{x}\left(1-{\frac {x^{2}}{2n}}+{\frac {x^{3}(8+3x)}{24n^{2}}}+\cdots \right),$

Too many capital letters

Hello. In this sort of edit, your using too many capital letters. I've changed it from Connection with Value at Risk to Connection with value at risk. This is required by Wikipedia:Manual of Style. Michael Hardy (talk) 22:56, 14 February 2010 (UTC)

I have marked you as a reviewer

I have added the "reviewers" property to your user account. This property is related to the Pending changes system that is currently being tried. This system loosens page protection by allowing anonymous users to make "pending" changes which don't become "live" until they're "reviewed". However, logged-in users always see the very latest version of each page with no delay. A good explanation of the system is given in this image. The system is only being used for pages that would otherwise be protected from editing.

If there are "pending" (unreviewed) edits for a page, they will be apparent in a page's history screen; you do not have to go looking for them. There is, however, a list of all articles with changes awaiting review at Special:OldReviewedPages. Because there are so few pages in the trial so far, the latter list is almost always empty. The list of all pages in the pending review system is at Special:StablePages.

To use the system, you can simply edit the page as you normally would, but you should also mark the latest revision as "reviewed" if you have looked at it to ensure it isn't problematic. Edits should generally be accepted if you wouldn't undo them in normal editing: they don't have obvious vandalism, personal attacks, etc. If an edit is problematic, you can fix it by editing or undoing it, just like normal. You are permitted to mark your own changes as reviewed.

The "reviewers" property does not obligate you to do any additional work, and if you like you can simply ignore it. The expectation is that many users will have this property, so that they can review pending revisions in the course of normal editing. However, if you explicitly want to decline the "reviewer" property, you may ask any administrator to remove it for you at any time. — Carl (CBM · talk) 12:33, 18 June 2010 (UTC) — Carl (CBM · talk) 13:30, 18 June 2010 (UTC)

Biconjugate Gradient Method

I recently saw that you removed my modifications from the Biconjugate Gradient page. I made the modifications because I implemented the way it was, and it did not worked. I double checked and the complex conjugates in the conjugate transpose counterparts of {p,r,x} are invalid.

Cross references in table at Fourier transform

Hi, you recent edits broke some of the cross-references at Fourier transform. Could you please fox the numbers in the table? Thanks. — Preceding unsigned comment added by 166.137.141.212 (talk) 23:08, 5 August 2011 (UTC)

Exponential function

Hello. About exponential function, you have added the error term of the function without reference. [1] Now, it is in question and needs some source. Could you provide some reference about it? If you could not point out, I am afraid that your paragraph will be removed. --Octra Bond (talk) 14:20, 11 August 2011 (UTC) test — Preceding unsigned comment added by 131.130.96.187 (talk) 06:03, 19 September 2011 (UTC)

October 2011

Welcome to Wikipedia. We welcome and appreciate your contributions, including your edits to Abel's summation formula, but we cannot accept original research. Original research also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. Thank you. Sławomir Biały (talk) 12:12, 10 October 2011 (UTC)

October 2012

Thank you for your recent contributions to the Euler summation article. While the Wikipedia community appreciates your efforts to increase the amount of information on the site, we cannot accept sources that appear to be the original work of the editor. If the material you added can be attributed to a reliable source, you may add it back if you cite it. This increases the reputation of Wikipedia as a whole and aids in the verifiability of the article. Sławomir Biały (talk) 22:33, 26 October 2012 (UTC)

Proposed deletion of J. Laurie Snell

The article J. Laurie Snell has been proposed for deletion because of the following concern:

No indication of how this might meet notability guidelines for academics.

While all constructive contributions to Wikipedia are appreciated, content or articles may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{proposed deletion/dated}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the article to address the issues raised. Removing {{proposed deletion/dated}} will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion.

Ways to improve Bishop–Phelps theorem

Hi, I'm Hz.tiang. A. Pichler, thanks for creating Bishop–Phelps theorem!

I've just tagged the page, using our page curation tools, as having some issues to fix. You might want to add in how this theorem can be applied.

The tags can be removed by you or another editor once the issues they mention are addressed. If you have questions, you can leave a comment on my talk page. Or, for more editing help, talk to the volunteers at the Teahouse. Hz. tiang 10:45, 27 September 2013 (UTC)

Laguerre polynomials

Hi. What exactly did you mean by ([2])

Moreover,

$y^{\alpha }e^{-y}D_{n}^{(\alpha )}(\,.,y)\rightarrow \delta (y-\,.)$, in the associated $L^{2}[0,\infty )$-space.

Do you meaan the limit as n goes to infinity? And I thought the Dirac delta "function" was not in $L^{2}[0,\infty )$. Eric Kvaalen (talk) 10:29, 2 January 2016 (UTC)

Speedy deletion nomination of Clare Crockett

If this is the first article that you have created, you may want to read the guide to writing your first article.

You may want to consider using the Article Wizard to help you create articles.

A tag has been placed on Clare Crockett requesting that it be speedily deleted from Wikipedia. This has been done under section G12 of the criteria for speedy deletion, because the page appears to be an unambiguous copyright infringement. This page appears to be a direct copy from https://www.sisterclare.com/en/her-life/biography. For legal reasons, we cannot accept copyrighted text or images taken from other web sites or printed material, and as a consequence, your addition will most likely be deleted. You may use external websites or other printed material as a source of information, but not as a source of sentences. This part is crucial: say it in your own words. Wikipedia takes copyright violations very seriously and persistent violators will be blocked from editing.

If the external website or image belongs to you, and you want to allow Wikipedia to use the text or image — which means allowing other people to use it for any reason — then you must verify that externally by one of the processes explained at Wikipedia:Donating copyrighted materials. The same holds if you are not the owner but have their permission. If you are not the owner and do not have permission, see Wikipedia:Requesting copyright permission for how you may obtain it. You might want to look at Wikipedia's copyright policy for more details, or ask a question here.

If you think this page should not be deleted for this reason, you may contest the nomination by visiting the page and clicking the button labelled "Contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be deleted without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines. Fram (talk) 09:32, 28 May 2020 (UTC)

Clare Crockett moved to draftspace

An article you recently created, Clare Crockett, does not have enough sources and citations as written to remain published. It needs more citations from reliable, independent sources. (?) Information that can't be referenced should be removed (verifiability is of central importance on Wikipedia). I've moved your page to draft space (with a prefix of Draft: before the article title) where you can work on it with minimal disruption. When you feel that it meets our notability and neutrality requirements, and is thus ready for mainspace, please submit it using the Articles for Creation template on the page. Justlettersandnumbers (talk) 09:48, 28 May 2020 (UTC)

Your submission at Articles for creation: Clare Crockett has been accepted

Clare Crockett, which you submitted to Articles for creation, has been created.

Congratulations, and thank you for helping expand the scope of Wikipedia! We hope you will continue making quality contributions.

The article has been assessed as Stub-Class, which is recorded on its talk page. It is commonplace for new articles to start out as stubs and then attain higher grades as they develop over time. You may like to take a look at the grading scheme to see how you can improve the article.

Since you have made at least 10 edits over more than four days, you can now create articles yourself without posting a request. However, you may continue submitting work to Articles for creation if you prefer.

If you have any questions, you are welcome to ask at the help desk. Once you have made at least 10 edits and had an account for at least four days, you will have the option to create articles yourself without posting a request to Articles for creation.

If you would like to help us improve this process, please consider .

Thanks again, and happy editing!
