Comment on article validity[edit]

This article is crap. For instance abelian varieties need not be over C, so they need not be complex tori, and I can certainly count Q-bar. Can someone more knowledgable with wikipedia put up the sign "In desperate need of expert review"?--unsigned

You would make a better impression if you adopted a more constructive tone, and also read the third sentence of the lead section. There is no need to put the most general sentence in the second sentence of an introduction. The 'algebraic definition' section down the page goes to the general field case; but the complex manifold case is important enough. Articles here do not strive initially for the greatest generality.

Your remark still doesn't make the sentence true. Nah well, I'll just refer people to the literature.--unsigned
Well, you could refer them to Mumford's Abelian Varieties, if you want a ridiculously steep learning curve. There they will find a definition as complete variety with group law - on p.39. Chapter One is all about the complex manifold instance. Rest my case. Charles Matthews 12:14, 22 March 2006 (UTC)


I have expanded and re-organized this article. It is still far from perfect so feel free to improve on it. It is my first (serious) contbutto wikipedia so comments and critique are most welcome. --Lenthe 13:52, 15 Jun 2005 (UTC)

Fantastic work. I'll try to find time later on to do my grammar-nazi thing. - Gauge 21:20, 17 Jun 2005 (UTC)

User:Charles Matthews I'm fairly new round here - I have created a number of new pages to fill gaps in mathematics. I'm finding the list of mathematical topics, which I believe people follow through the 'related changes', somewhat clunky. I believe as a good citizen I should be adding to this the new pages, and also unlinked pages that I come across. Well, I have done some of that, but the page is very big at well over 100K.

Also, as in the case of 'Abelian variety' which was on the LOMT already and for which I made a page, it seems that the Related Changes doesn't flag that as a new page on its creation. This seems odd, in the case of a 'wanted' page.

This is a confusing piece. You could define words so that it is clear what is the same as what.


I'm sort of a novice, but in the section on the algebraic defintion, isn't it true that all abelian varieties are projective (ie. over any field, not just complex) CraigDesjardins 14:45, 1 July 2006 (UTC)

That is correct, and is also what was intended in the article. I have changed the wording slightly, hoping to avoid confusion. --Lenthe 10:12, 7 August 2006 (UTC)
