[edit] help request

{{helpme}} I don't know where to ask this: Is there a skin which hides the Wikipedia logo, and all the rest of the left column (or even better, shows it when I hover the mouse to the left part of the browser window)? Thanks for helping me out. Jakob.scholbach (talk) 16:55, 28 April 2008 (UTC)

Well, it's just bothering me (I never use any of the links in the column. Is there a group of users working on the skins etc.? People fooling around with the monobook.css file? Thanks. Jakob.scholbach (talk) 19:10, 28 April 2008 (UTC)

Also, is it possible to somehow show a list of recently watched WP articles? Jakob.scholbach (talk) 16:56, 28 April 2008 (UTC)

  • Questions like this can be asked over at Wikipedia:Village pump (technical). When you print a Wikipedia page, it does not include the left-hand column, so there must be a way of making that column disappear. EdJohnston (talk) 20:45, 28 April 2008 (UTC)
  • I use the "chick" skin. It is lightweight and easy to customize. It starts out kind of ugly and useless, but that is just because they don't force you to override their style. I put the tools I use at the top of the page, and compress the others on the bottom. You can check out User:JackSchmidt/chick.css to see my view. For my work mediawiki, I removed the lefthand column in monobook. This is surprisingly hard to do in a browser independent fashion, because mediawiki has quite a lot of of browser hacks in the monobook skin. In particular, I was not able to do it from a user CSS file. WP:VP/T is definitely a good place to ask questions, especially about special pages. JackSchmidt (talk) 20:52, 28 April 2008 (UTC)
Thanks to all of you! Jack, I tried adding your chick.css to my monobook.css which rendered the page hard to use (for example the "edit this page" link was still there, but I could not access it with the mouse) and the content of the left hand column was still there, but in a disordered manner. I undid this and then I tried to created a file called "chick.css" and filled it with the content of your chick.css, but this did not give any change (as I think it should not). Do I need to load another script or something? Where is this chick style from? Jakob.scholbach (talk) 21:19, 28 April 2008 (UTC)
Yeah, you want it in chick.css not monobook.css. I might have a monobook.css to kill some of the spam, but I don't update it as frequently as the spammers. You go to Special:Preferences and select the Chick skin, under the "Skins" tab. JackSchmidt (talk) 21:28, 28 April 2008 (UTC)
Thanks, now I get it. Jakob.scholbach (talk) 16:26, 29 April 2008 (UTC)

[edit] My geometry bias

Just to give you an idea of how pervasive the idea of geometry is in group theory (or at least how completely my bias has warped my vision), consider Lagrange's theorem, your typical 18th century group theory result. Originally, it was about the symmetries of a rational univariate polynomial, one of the nicer 0-dimensional geometric objects. In the modern formulation, it is about the symmetries of the coset space (a particularly bland geometry in the general case, but also called the grassmannian, flag manifold, or Borel variety in some important cases). The reason the order of a subgroup divides the order of the group, is because the group is itself the set of points of a geometry, and the blocks of that geometry are the cosets of the subgroup. The group acts as isometries, so each coset is the same size, and so the order of the group is a multiple of the order of the subgroup.

One of Jacques Tits major contributions to group theory is the recognition that this sort of "coset geometry" can be the foundation for an understanding of finite groups. These days people are always trying to find pretty geometries for important groups to act on. Usually the cohomology of the group is more or less the same as the cohomology of the geometry, and the geometry might be homotopic to something easier to deal with (say the geometry of a much smaller group, or of an n-sphere).

How to add this information to wikipedia? No clue. It is easy to source, but probably will sound too technical. It would definitely confuse undergrad algebra students. It would likely get confused by crystallographer's ideas of symmetry. JackSchmidt (talk) 21:55, 13 May 2008 (UTC)

[edit] Wooo, GA

Congratulations. You've spearheaded the effort to get the group article to GA status, and User:Wafulz just passed it! JackSchmidt (talk) 19:04, 14 May 2008 (UTC)

Thanks for the congrats and thanks for your working on the article! I already said to GGuy: I truly appreciate this atmosphere here, working with highly knowledgeable people (like you and him, for example) on a goal without reward other than the work itself.
Settling the remaining issues pointed out by Geometry guy, developing group theory and possibly running for FA will be enough work for the weeks to come. Jakob.scholbach (talk) 20:57, 14 May 2008 (UTC)

[edit] Attacks

I have removed the section at WT:MATH because it consists almost entirely of attacks on myself. Please do not replace it. It serves no useful purpose to any wp content. I would like to diffuse this situation, not continue it. This is a request. Be well, Pontiff Greg Bard (talk) 15:24, 1 June 2008 (UTC)

If it had not yet been done by somebody else, I would redo my restoring of the thread. I'm not interested in the discussion, but deleting material which has not been posted exclusively by yourself is out of the question. If you are convinced that others are doing wrong to you, you should seek support from the community. Deleting content will provoke the adverse reaction, though.

[edit] Translation of Emmy Noether article titles?

Jakob, since you obviously have some skills with German, I wonder if you'd be willing to help us out at Emmy Noether, which is currently at FAC. It's been suggested that we provide translations for Dr. Noether's articles, and this is way over my head. Any assistance you can provide would be appreciated. (If you like, I'll even compile a list of German titles – in my sandbox, perhaps – and you can just pop them in there.) Otherwise, can you recommend someone maybe? Thanks in advance. – Scartol • Tok 16:55, 1 June 2008 (UTC)

Yes, I'm German. So here are the translations.
Über minimale Zerfällungskörper irreduzibler Darstellungen = On minimal splitting fields of irreducible representations
Beweis eines Hauptsatzes in der Theorie der Algebren = Proof of a main theorem in the theory of algebras
Rationale Funktionenkörper (misses the ö in the article!) = Rational function fields
Gleichungen mit vorgeschriebener Gruppe = Equations with prescribed group / groups (I don't know what is correct in English here. Orginial is singular)
Invariante Variationsprobleme Invariant variation problems
Idealtheorie in Ringbereichen = Ideal theory in domains
Der Endlichkeitsatz der Invarianten endlicher linearer Gruppen der Charakteristik p = The finiteness theorem of invariants of finite linear groups of characteristic p
Abstrakter Aufbau der Idealtheorie in algebraischen Zahl- und Funktionenkörpern = Abstract composition of ideal theory in algebraic number [fields] and function fields
Hyperkomplexe Grössen und Darstellungstheorie = Hypercomplex quantities and representation theory
Nichtkommutative Algebren = Noncommutative algebras
As an aside, I suggest that you format the ref section into her work and secondary sources etc. I also suggest that you supply the urls of the historical papers. (See my comment at the article's talk page). Doing this does not require mathematical knowledge :) just browse http://digizeitschriften.de and find it. Practically all historical papers are available. I will put the latter comment to the FAC discussion, too. Good luck! Jakob.scholbach (talk) 17:09, 1 June 2008 (UTC)
I missed one
Die Struktur der R. Brauerschen Algebrenklassengruppe über einem algebraischen Zahlkörper = The structure of R. Brauer's algebra class group over an algebraic number field Jakob.scholbach (talk) 17:19, 1 June 2008 (UTC)
Wunderbar! Thanks so much for these. I'm in your debt. I think you're right about reorganizing the refs into primary and secondary sources, as well as linking. I'll work on it. Thanks again. – Scartol • Tok 17:48, 1 June 2008 (UTC)
Hmm. I went to the site and tried searching for "Rationale Funkionenkorper" and "Über minimale Zerfällungskörper irreduzibler Darstellungen" – both came back with "0 Treffer", which I assume means "0 Results". Thoughts? – Scartol • Tok 17:52, 1 June 2008 (UTC)
I'm in a hurry, but check out [1] to see all works authored by NOether. The second one really seems to miss, the first one: you need to spell it correctly (kÖrper instead of kOrper). Jakob.scholbach (talk) 18:24, 1 June 2008 (UTC)

Understood. I'll stop bugging you now. have a Barnstar. – Scartol • Tok 18:28, 1 June 2008 (UTC)

The Rosetta Barnstar
For your speedy translation of Emmy Noether titles, I offer this token of thanks. – Scartol • Tok 18:28, 1 June 2008 (UTC)
Oh, wow. In German we say: That wouldn't have been necessary. Was a pleasure to help out. Probably I will get back to your for some copyedit help on groups. Have a nice day, Jakob.scholbach (talk) 09:37, 2 June 2008 (UTC)
