Surgery Theory
Dr.Ranicki,

The page on Surgery theory is not very well-developed. If you could lend any kind of assistance in getting it into shape, it would be extremely helpful. Thanks, Artie P.S. 10:27, 2 April 2007 (UTC)

Hauptvermutung confusion
I switched H3 and H4 in Hauptvermutung back to what they were before your edit. One of my sources for this is the article listed in the references by a certain "A. Ranicki". R.e.b. 03:41, 13 April 2007 (UTC)

Hello. Please don't forget to provide an edit summary. Thanks, and happy editing. --Berland 09:50, 26 September 2007 (UTC)

Thanks
Hi, Andrew. Thanks for your additions to the article on surgery theory. It's nice to have experts helping out. (By the way, we've never met, but Bruce Hughes was my undergraduate thesis adviser at Vanderbilt.) VectorPosse 20:04, 30 November 2007 (UTC)

Image source problem with Image:C.T.C.Wall.jpg
Thanks for uploading Image:C.T.C.Wall.jpg. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, you will need to specify the owner of the copyright. If you obtained it from a website, then a link to the website from which it was taken, together with a restatement of that website's terms of use of its content, is usually sufficient information. However, if the copyright holder is different from the website's publisher, their copyright should also be acknowledged.

If you have uploaded other files, consider checking that you have specified their source and tagged them, too. You can find a list of files you have uploaded by following this link. Unsourced and untagged images may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If the image is copyrighted under a non-free license (per Fair use) then the image will be deleted 48 hours after 11:50, 25 November 2008 (UTC). If you have any questions please ask them at the Media copyright questions page. Thank you. Peripitus (Talk) 11:50, 25 November 2008 (UTC)

Category:Surgery theory
Hi! There is a discussion ongoing at Wikipedia talk:WikiProject Mathematics regarding the appropriateness of the category Category:Surgery theory for certain mathematics articles. Some things seem a bit overcategorized, like manifold, which should probably be in a supercategory of surgery theory, than in the category itself. Please contribute to the discussion there, as I am eager to see this matter resolved to everyone's satisfaction. siℓℓy rabbit (  talk  ) 15:43, 14 December 2008 (UTC)

Atiyah's birthday conference
The article on Michael Atiyah has had a link to his birthday conference in the external links section for several months. There is no need to keep adding a second copy of the link. r.e.b. (talk) 14:20, 28 April 2009 (UTC)

The links were in fact different, but there is a link in the second link to the first link, so I have removed the first link.ranicki (talk) 06:19, 29 April 2009 (UTC)

Bibtex to WP
I designed http://toolserver.org/~verisimilus/Scholar/Cite.php to convert from Bibtex, but I haven't been maintaining it. Let me know if you can get it to work! Martin  (Smith609 – Talk)  21:14, 16 May 2009 (UTC)

Hello again
Well, goes back to DPMMS thirty years ago and more. The issue at cobordism, for me, is not so much the mathematics as getting the article structure sorted out. Given the right organisation, it usually follows that expansion a section at a time is unproblematic. By the way, could you use edit summaries? It generally makes life easier all round. Also you might want to take your email down from your userpage: people can email you via the sidebar link, so you can reduce spam without preventing communication.

Speedy deletion nomination of Manifold Atlas Project
A tag has been placed on Manifold Atlas Project requesting that it be speedily deleted from Wikipedia. This has been done under section A7 of the criteria for speedy deletion, because the article appears to be about web content, but it does not indicate how or why the subject is important or significant: that is, why an article about that subject should be included in an encyclopedia. Under the criteria for speedy deletion, such articles may be deleted at any time. Please see the guidelines for what is generally accepted as notable, as well as our subject-specific notability guideline for web content. You may also wish to consider using a Wizard to help you create articles - see the Article Wizard.

If you think that this notice was placed here in error, you may contest the deletion by adding  to the top of the page that has been nominated for deletion (just below the existing speedy deletion or "db" tag - if no such tag exists then the page is no longer a speedy delete candidate and adding a hangon tag is unnecessary), coupled with adding a note on the talk page explaining your position, but be aware that once tagged for speedy deletion, if the page meets the criterion, it may be deleted without delay. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the page that would render it more in conformance with Wikipedia's policies and guidelines. Lastly, please note that if the page does get deleted, you can contact one of these admins to request that they userfy the page or have a copy emailed to you.

Elmar Winkelnkemper
Whether you recuse yourself from the discussion or not, I thought you should be informed of the deletion discussion concerning the article Elmar Winkelnkemper. Best, Sławomir Biały  (talk) 20:06, 3 October 2010 (UTC)

File permission problem with File:Surgery and morse function.png
Thanks for uploading File:Surgery and morse function.png. I noticed that while you provided a valid copyright licensing tag, there is no proof that the creator of the file agreed to license it under the given license.

If you created 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 , 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 .

If you believe the media meets the criteria at Non-free content, use a tag such as or one of the other tags listed at File copyright tags, and add a rationale justifying the file's use on the article or articles where it is included. See 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 the Wikipedia's image use policy. If you have any questions please ask them at the Media copyright questions page. Thank you. Magog the Ogre (talk•edits) 17:51, 13 August 2012 (UTC)

Cobordism question
Hi! I just edited Cobordism a bit and found your addition of Thom's result about the unoriented cobordism groups:


 * In 1954 René Thom computed
 * $$\Omega_n^{\text{O}}=\mathbf Z_2[x_i \vert i \geq 1, i \neq 2^j -1 ]$$
 * with one generator xi in each dimension i ≠ 2j−1.

I don't quite understand the statement; for instance, how many generators does $$\Omega_n^{\text{O}}$$ have? It seems the LHS depends on n while the RHS depends on j. Cheers, AxelBoldt (talk) 01:19, 4 February 2013 (UTC)

I have revised the section on unoriented cobordism, now using Thom's original terminology, and giving a more detailed account of the computation. ranicki (talk) 07:31, 4 February 2013 (UTC)
