[edit] Welcome

Hi, and welcome! And a few tips. One is that it is good to use an edit summary when you contribute, so that others understand what you changed. Also, it is good to put a bit more care into formatting, rules of punctuation, space after period and comma, etc., so that the end result looks nice. Enjoy! Write to me if you have any questions.

[edit] Variational number theory

Hello. Questions have arisen on the verifiability of the article on variational number theory, which you wrote. Unfortunately, we have been unable to locate the book mentioned in the references. The ISBN seems to be invalid. Could you please check the details and add the year of publication? It would also be helpful if you could mention another reference. Thanks. -- Jitse Niesen (talk) 13:12, 7 May 2006 (UTC)

I have nominated variational number theory for deletion, for the reasons described on Wikipedia:Articles for deletion/Variational number theory. You may wish to comment on that page. -- Jitse Niesen (talk) 14:14, 23 May 2006 (UTC)

Please stop. If you continue to create inappropriate pages such as variational number theory, you will be blocked from editing Wikipedia. . It's been deleted three times now. — Arthur Rubin | (talk) 21:35, 26 July 2006 (UTC)

Also, I'm afraid I used the [rollback] admin function to revert some of your edits of other articles; that was incorrect on my part, except for those parts adding references to variational number theory. The edit description should have been "revert incorrect or misleading references", or something along those lines. Feel free to add back in material I deleted in those articles, if you feel that I made a mistake. — Arthur Rubin | (talk) 19:30, 28 July 2006 (UTC)

[edit] Style tip

Just a note. The section name instead of

==Perron,s Formula==

should be

==Perron's formula==

So, instead of the comma there is apostrophe, per normal English rules, and there should be small "f" in formula per the style manual. Thanks. You can reply here if you have comments. Oleg Alexandrov (talk) 22:59, 23 May 2006 (UTC)
