Please do not add unsourced or original content, as you did to Real algebraic geometry. Doing so violates Wikipedia's verifiability policy. If you continue to do so, you may be blocked from editing Wikipedia. — Duncan What I Do / What I Say 09:53, 26 July 2010 (UTC)

Hello there. Over at real algebraic geometry, I see what you're trying to do. But a couple of times you have cut out sections, and this was presumably not intentional. Charles Matthews (talk) 10:05, 26 July 2010 (UTC)

I have some experience with wikis both not with Wikipedia. All comments are welcome.


 * OK, I'll look at the article later, and leave comments on Talk:Real algebraic geometry. Charles Matthews (talk) 12:24, 26 July 2010 (UTC)

Positive polynomial
Please look at my recent edits to positive polynomial. You should never start a Wikipedia article by saying "Let p be a....", etc., the way you might if you're writing for an audience of mathematicians. At the very least, some introductory words should tell the lay reader that mathematics is what the article is about before you do things like that. Usually the title word or title phrase should be set in bold at its first appearance, usually in the first sentence. Also, I've changed the title of the article so that it is singular. Manual of Style says the singular should be used except when there is a special reason to use the plural (e.g. when the article is about a set of things, such as The Beatles or Maxwell's equations).

Also, you should notice WP:MOSMATH. In particular:
 * In non-TeX mathematical notation, variables are italicized by digits and parentheses are not. This matches TeX style.
 * In non-TeX notation, a space precedes and follows things like "+", "=", "<", etc. (In TeX, the software takes care of the spacing so you don't need to attend to it.)
 * A minus sign is longer than a stubby little hyphen: 5 &minus; 3 = 2, not 5 - 3 = 2. (This also doesn't apply to TeX, which renders a hyphen in math mode as a minus sign.)
