[edit] Perl

Thanks for that well-documented factoid concerning Perl! :) --Otheus 21:58, 1 April 2007 (UTC)

[edit] Punctuation

Hello. You replied to my posting at the Help Desk for Language. I replied to you (there):

Wow. This is more complex than I thought. Tesseran, you made the statement: "Indeed, it is not even a valid sentence in written English (for a number of reasons, main among which is the punctuation issue)." Why exactly is my Sentence 3 not a valid English sentence? Please expand on that. Thanks. (JosephASpadaro 03:53, 19 June 2007 (UTC))

[edit] Klein quartic

Do you have a source for the claim that the Klein quartic is defined by a congruence relation modulo 7? Also, the congruence relation is not defined in the real context. Katzmik 09:20, 31 July 2007 (UTC)

There is an error here. A subgroup of PSL(2,Z) would give a complete Riemann surface but not a compact one. To get the compact form of the Klein quartic rather than an affine slice, one needs a more elaborate arithmetic set-up. Katzmik 09:10, 1 August 2007 (UTC)

It would make sense to continue the discussion on the Klein quatric "discussion" page. I will place a comment about affine versus compact there. Katzmik 12:18, 1 August 2007 (UTC)

[edit] Request for edit summary

Hi there. 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. If you are adding a section, please do not just keep the previous section's header in the Edit summary field - please fill in your new section's name instead. Thank you. – Oleg Alexandrov (talk) 04:05, 25 August 2007 (UTC)

[edit] Your question on maths refdesk

You asked the following question as an aside:

Also, Lambiam, your link includes the following: A couple of theorems are relevant here, I guess: first, given any group G there is a group of rotations in SO(n) isomorphic to G as long as n is sufficiently large. Does anyone have a reference for this surprising result? (Or, if it's false, what is the appropriate restriction? Finitely generated group? Lie group? Finite group?) Tesseran 16:56, 29 August 2007 (UTC)

Since that discussion was long enough already, I thought I should answer here. This result is trivially false: R^n has the cardinality of R, so SO(n) has cardinality at most card(Powerset(R)), but groups can be arbitrarily large (take the free group on loads of generators, or something). I think some version of Weyl's unitary trick might prove this for finite groups, but I haven't checked the details. Don't quote me, because I'm drunk. Algebraist 23:21, 30 August 2007 (UTC)

Oh yeah, I know the cardinality of SO(n). I just thought the above was slightly simpler. In case you haven't done it, I checked the details after sobering up; it works. Algebraist 15:46, 6 September 2007 (UTC)

[edit] RD Language reply

I've replied to your "reply" in the RD. I'm (still) assuming you're a legitimate user. --Taraborn 02:36, 27 September 2007 (UTC)

Okay, now I understand. Sorry for any misunderstandings I may have caused. --Taraborn 12:03, 27 September 2007 (UTC)

[edit] Academy Award

Hi. You answered my question at the Language Help Desk. This one:Wikipedia:Reference desk/Language#Semantics. Thanks. So, what exactly is the difference between one "shared" award versus two "separate" awards? Everyone walks away with an Oscar trophy, no? I'm confused. Please reply at my Talk Page. Thanks.
