# Talk:Typographical conventions in mathematical formulae

As found in Roman letters used in mathematics votes for deleation article, this article was the brainchild of mikka, and the two links on the article is my idea. I think both are good ideas and both this article and my two articles should be merged!

## American and European differences

I've added some rudimentary information on American mathematical typography. I wish I could locate Knuth's lecture notes on "Mathematical typography"; I found a PDF of them online one time, but don't remember where.

Please add more information about mathematical typography, and in particular about the parts that are different between American and European style. For example, I'm given to understand that many European journals use upright Latin letters and/or italic Greek letters?

I don't know if this article should turn into "dos and don'ts of math writing," but if it does, I've got plenty. :) --Quuxplusone 22:56, 3 Jun 2005 (UTC)

- I'm European, but I've no idea how European conventions should differ from what's presented as American in the article. (I must confess I've never publshed anything in a European journal, however.) Is there really any difference here? (Well, I say and you say ; I say 0,5 and you say 0.5 - so let's call the whole thing off... But other than taht?)--Niels Ø (noe) (talk) 21:58, 21 December 2007 (UTC)

## mathematization joke

I noticed the red link "mathematization" joke. Did this exist before? I think somewhere a bit more should be said about that. E.g. the standard use (almost "meaning") of \epsilon, and also e.g. "x,y" for real variables against "k,m,n,..." for integer variables. (Just ran across the latter). Information on this is quite dispersed; this page and other existing pages (Roman letters used in mathematics) are not featured richly enough on this, imho. — MFH:Talk 17:30, 29 March 2006 (UTC)

## Typographical conventions or notational conventions

Although the topics may have some overlap, I think it is worthwhile to distinguish between typographical conventions (how formulae are actually typeset: how the font size of a superscript relates to the main text; when three dots are raised or on the baseline; where thin spaces are inserted; ...) and general conventions in mathematical notation (such as the use of single-letter names for variables, but multi-letter names for specific functions and operators; various uses of super- and subscripts; parentheses; function application; infix|postfix|ambifix operators; ellipses; abuse of notation; ...). In my opinion the latter topic — conventions in mathematical notation — warrants a separate article. Lambiam^{Talk} 03:13, 5 April 2006 (UTC)

- Point well taken, Lambiam!—PaulTanenbaum (talk) 03:03, 13 April 2008 (UTC)

## Mathematical Joke

I can't find this joke anywhere? What is it? The Roc 1217 06:32, 6 April 2007 (UTC)

Yes, please tell us the joke. It's not fair to tease like that. 130.231.106.133 (talk) 12:27, 18 March 2008 (UTC)

## Globalize

I've added a Globalize tag since this article explicitly states repeated that the conventions apply only to America. However I'm not actually convinced that they do (!) and if anyone can give an authoritative answer saying that they are not then we can probably remove the tag. --Neil (talk) 09:59, 1 June 2009 (UTC)
