Lebesgue Integration

All this talk of integration strikes me as inapproprite for a biography of Lebesgue, which is what this article ought to be. It's nice that User:The_Anome is destubbing it; it's just that the test that (s)he is writing ought to be in the article Lebesgue_integration instead. After all, Lebesgue did a lot more than just this integral, and we'll want to write about that in here eventually. I'm not saying that The Anome's text is bad, not at all, only that it's in the wrong article. — Toby Bartels, Wednesday, July 10, 2002

Dissertation Length

Is it true that Lebesgue's dissertation about the Lebesgue integral was just 3 pages long? That should be mentioned, if confirmed.—Preceding unsigned comment added by 63.203.206.121 (talk) 07:01, 28 May 2005

Pronunciation

How is this name pronounced? I have never heard it before; a pronunciation guide would be helpful. --LostLeviathan 05:48, 25 November 2005 (UTC)[reply]

LEH-BEG. The "s" is silent.—Preceding unsigned comment added by 71.35.54.72 (talk) 12:21, 28 November 2005

The IPA representation is fine, but an English approximation would be more useful. C Clingen (talk) 14:17, 16 March 2008 (UTC)[reply]

Etymology

In French, le bègue means "the stutterer". I'm guessing this is the etymology of Lebesgue's name, but I'm not sure. Does anyone have evidence to this effect? --Siva 04:01, 5 September 2006 (UTC)[reply]

Infobox

I've added an infobox to this article together with information contained in the piece or very obviously available through the external links on the page. I've left the flag needs-infobox to yes despite this as some important fields remain empty. Specifically: caption (I've found no history behind this photo giving a context); alma_mater (probably ENS, Paris but I've not seen this explicitly stated as the explicit issuer of his PhD - there is a ref. to Poincare tho') and work_institutions. Depending on how the article develops prizes and footnotes may also be important. -- Asperal 16:24, 25 June 2007 (UTC)[reply]

Thanks for doing that. If you've found no history on the photograph, it might be better to replace it with an older one, as this one isn't obviously old enough to be public domain. See my talk page for more info. Geometry guy 14:58, 27 June 2007 (UTC)[reply]

Cronholm added the alma mater. Is there anything else needed, or can we remove the needs-infobox tag now? Geometry guy 20:02, 27 June 2007 (UTC)[reply]

My view is that the addition of the alma-mater is sufficient to remove the infobox tag. As I added this tag I've now removed it. Thank you, Asperal 21:28, 28 June 2007 (UTC)[reply]

A quick search on Wikimedia Commons found the, already loaded, other image you mentioned of Henri Lebesgue. I've switched the reference in this document to that earlier picture. Please feel welcome to make further changes, or remove, if there might be copyright concerns. Asperal 11:52, 29 June 2007 (UTC)[reply]

I wrote a new section, copyediting is welcome. Also I am not sure this article is quite B-class yet. --Cronholm¹⁴⁴ 21:36, 27 June 2007 (UTC)[reply]

Also, I agree with G-guy that the informal discussion of integration really doesn't belong in this article. Thought?--Cronholm¹⁴⁴ 21:47, 28 June 2007 (UTC)[reply]

Completely agree. The section on integration, for this article, only needs to go so far as to cover it's relevance to the individual. There is already an article section covering the general history. Asperal 11:52, 29 June 2007 (UTC)[reply]

L1 or continuous

The article states: "He also proves that the Riemann-Lebesgue lemma is a best possible result for continuous functions"

Surely this is supposed to be L^1 functions, rather than continuous? Otherwise, I'm not sure what the content of the sentence is supposed to mean.--74.132.206.251 (talk) 01:30, 12 December 2007 (UTC)[reply]

Birthplace

According to this article, Lebesgue is born in both Beauvais and Rennes, but aren't those two different places? If that is the case, then surely something is wrong. --pred (talk) 16:52, 16 December 2007 (UTC)[reply]

surfaces applicable to a plane

Section 2 on "Mathematical career" has the following in the fourth line: "The next five dealt with surfaces applicable to a plane, the area of skew polygons, surface integrals of minimum area ...". The word "applicable" is probably erroneous translation from French, and the correct phrase replacing it should probably be "mappable in a one-to-one way", or in better English, it should be written as "surfaces that can be mapped into the plane in a one-to-one way". I don't really know, because I don't have the French title in front of me. In any case, the word "applicable" does not make good sense here, whereas the analogous word in French would make good sense. Someone should correct this.

"teilweise heftig" mistranslation

The phrase "... calls it the `teilweise heftig`" is not correct; "teilweise heftig" means "sometimes violently" in german, so ".. refers to [the controversy] as being `somewhat violent`" would be more correct I guess. There's a brief mention of this on page 69 in the Jerzy Neyman bio (see http://books.google.com/books?id=RIt1bKo0j58C )
