Moscow Cathedral Mosque and Moscow Choral Synagogue

Regarding your creation of the Moscow Cathedral Mosque and Moscow Choral Synagogue articles, you accidentally added the "{{Categorize}}" template to them, despite having categorized them according to the WP guidelines. This isn't really necessary, and creates an artificial additional backlog in the Category needed category, which is backed up as it is. LeaHazel : talk : contribs 23:19, 5 December 2006 (UTC)

I am not sure I've categorized them properly.--Planemo 23:21, 5 December 2006 (UTC)

I see. I did narrow down the category on one of the articles from Category:Mosques to Category:Mosques in Russia, but the Categorize template is designated for articles that have no categories at all. Once you've added an article to a category, it's accessible to people who've edited Wikipedia longer, or know that specific subject better, and they can sometimes provide a more accurate categorization. When in doubt, it's better to include an article in a wider category, rather than adding it to the back-logged uncategorized queue. LeaHazel : talk : contribs 23:55, 5 December 2006 (UTC)

Request for edit summary

When editing an article on Wikipedia there is a small field labeled "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.

Filling in the edit summary field greatly helps your fellow contributors in understanding what you changed, so please always fill in the edit summary field, especially for big edits or when you are making subtle but important changes, like changing dates or numbers. Thank you. – Oleg Alexandrov (talk) 17:33, 9 December 2006 (UTC)

Chain rule

I reverted your change to the chain rule. It made it harder to apply that formula below in the article, I think. Oleg Alexandrov (talk) 17:40, 9 December 2006 (UTC)

Let's it be the both formulae.--Planemo 20:12, 9 December 2006 (UTC)

Athenian Curvature

I've read your edits in Affine curvature about Athenian curvature... I must confess, this not something I've come across in my studies, nor Athenian transformations. as I can't find anythign about it on the net, could you possibly provide a reference? Cheers :-) Tompw (talk) 20:21, 10 December 2006 (UTC)

Inverse function

Hi. I reverted your changes to Inverse function for two reasons. One, you switched to a new "inv" notation in the middle of the article which was not defined. That can be confusing. Second, the formula you put there, for the derivative of the inverse, is not really appropriate, since all that article deals with general functions between sets, and the formula for the inverse of the derivative holds only for differentiable functions of a real variable (the way you wrote it at least).

In short, your changes while correct, were not in the right context, I think. You can reply here if you have comments. Thanks.

And by the way, could you please use an edit summary when you contribute? Thanks. Oleg Alexandrov (talk) 15:43, 18 December 2006 (UTC)

I've added the description--Planemo 16:01, 18 December 2006 (UTC)

I disagree with adding a new "inv" notation. One should be consistent throughout the article, and there is really no need for a new notation I think, it just confuses things. I put back the more accepted "^-1" notation. Oleg Alexandrov (talk) 16:02, 18 December 2006 (UTC)

I am ok with this but your notation may be confusing with power indicator.--Planemo 16:04, 18 December 2006 (UTC)

That is not my notation. That is the standard notation used in all math textbooks. And it is not similar at all to the indicator notation, which is as far as I know $1_{X}.$ Oleg Alexandrov (talk) 03:44, 19 December 2006 (UTC)

I meant indicator of power показатель степени. Вашу нотацию легко спутать с показателем минус первой степени.--Planemo 04:50, 19 December 2006 (UTC)

Это не моя нотация. Oleg Alexandrov (talk) 16:36, 19 December 2006 (UTC)

Rigor needed

Regarding your addition of "Series form" to inverse function, it is not clear

• What kind of function f is (linear, nonlinear, differentiable, analytic)

  analytic.

• What kind of variable x is (real, complex, $\mathbb {R} ^{n}$, Banach space)

  where do you see x there? The function is supposed to be f(t)

• What kind of convergence you are talking about (pointwise, uniform, what norm)

  In the point t. Given t and f it gives inv f(t)

• Where is the variable t?

  t is the argument of the both f and inv f. It can be interpreped as тождественная функция, то есть, функция, от применения которой аргумент не меняется ($t\circ f=f,f\circ t=f$). It is simple: you have f(t) and you get inv f(t). When the argument is simply t, it is generally ommitted: instead of f(t) write simply f.

I understand your intention, but that text is poorly written. Can you also provide a reference for that formula (a book?)

This formula is easily derived.--Planemo 21:08, 19 December 2006 (UTC)

I would suggest you use more care when contributing. Let us do math at a serious level. Thanks. Oleg Alexandrov (talk) 16:46, 19 December 2006 (UTC)

You see, if you don't clarify all this in the article, your addition has no value. If you leave it that way, I will remove that section. Не хальђурь. :) Oleg Alexandrov (talk) 03:34, 20 December 2006 (UTC)

Hmmm. What clarification is needed? It is common practice to ommit arguments when left and right parts use the same. Don't you agree? If you dont like using "t" variable, it can be easily changed to "x". Or might I did not understand something...--Planemo 04:14, 20 December 2006 (UTC)

That article is about the inverse of a general function, in a set theory framework. You inserted a formula which is valid for only very special functions, on the real line, and did not bother to explain when that formula is valid.

Both before and after your formula the discussion is about fully general functions. Your text stands in the middle, very confusing and unclear. I see it got deleted.

If you want to put it back, please put it at the end of the article, explain for what kind of functions it is valid (what their domain is, their range, what type of functions).

But really, I think your text is not valuable in that article. I may delete it anyway. Oleg Alexandrov (talk) 15:56, 20 December 2006 (UTC)

Replaceable fair use Image:RyazanBT.jpg

Replaceable fair use

Thanks for uploading Image:RyazanBT.jpg. I noticed the description page specifies that the media is being used under fair use, but its use in Wikipedia articles fails our first fair use criterion in that it illustrates a subject for which a freely licensed media could reasonably be found or created that provides substantially the same information. If you believe this media is not replaceable, please:

1. Go to the media description page and edit it to add {{di-replaceable fair use disputed}}, without deleting the original Replaceable fair use template.
2. On the image discussion page, write the reason why this image is not replaceable at all.

Alternatively, you can also choose to replace the fair use media by finding freely licensed media of the same subject, requesting that the copyright holder release this (or similar) media under a free license, or by taking a picture of it yourself.

If you have uploaded other fair use media, consider checking that you have specified how these images fully satisfy our fair use criteria. You can find a list of description pages you have edited by clicking on this link. Note that even if you follow steps 1 and 2 above, fair use media which could be replaced by free-licensed alternatives will be deleted 2 days after this notification (7 days if not used in an article), per our Fair Use policy. If you have any questions please ask them at the Media copyright questions page. Thank you. Rettetast (talk) 20:00, 1 January 2008 (UTC)

Orphaned non-free media (File:Moscow Cathedral Mosque.jpg)

Thanks for uploading File:Moscow Cathedral Mosque.jpg. The media description page currently specifies that it is non-free and may only be used on Wikipedia under a claim of fair use. However, it is currently orphaned, meaning that it is not used in any articles on Wikipedia. If the media was previously in an article, please go to the article and see why it was removed. You may add it back if you think that that will be useful. However, please note that media for which a replacement could be created are not acceptable for use on Wikipedia (see our policy for non-free media).

If you have uploaded other unlicensed media, please check whether they're used in any articles or not. You can find a list of 'image' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "Image" from the dropdown box. Note that all non-free media not used in any articles will be deleted after seven days, as described on criteria for speedy deletion. Thank you. BJBot (talk) 05:02, 17 January 2009 (UTC)

File permission problem with File:Pluto structure small.gif

Thanks for uploading File:Pluto structure small.gif. I noticed that while you provided a valid copyright licensing tag, there is no proof that the creator of the file has agreed to release it under the given license.

If you are the copyright holder for this media entirely yourself but have previously published it elsewhere (especially online), please either

• make a note permitting reuse under the CC-BY-SA or another acceptable free license (see this list) at the site of the original publication; or
• Send an email from an address associated with the original publication to permissions-en@wikimedia.org, stating your ownership of the material and your intention to publish it under a free license. You can find a sample permission letter here. If you take this step, add {{OTRS pending}} to the file description page to prevent premature deletion.

If you did not create it entirely yourself, please ask the person who created the file to take one of the two steps listed above, or if the owner of the file has already given their permission to you via email, please forward that email to permissions-en@wikimedia.org.

If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as {{non-free fair use}} or one of the other tags listed at Wikipedia:File copyright tags#Fair use, and add a rationale justifying the file's use on the article or articles where it is included. See Wikipedia:File copyright tags for the full list of copyright tags that you can use.

If you have uploaded other files, consider checking that you have provided evidence that their copyright owners have agreed to license their works under the tags you supplied, too. You can find a list of files you have created in your upload log. Files lacking evidence of permission may be deleted one week after they have been tagged, as described on criteria for speedy deletion. You may wish to read Wikipedia's image use policy. If you have any questions please ask them at the Media copyright questions page. Thank you. Kelly ^hi! 19:22, 7 December 2015 (UTC)
