I'm removing the reference to Riemannian geometry, since this is a subcategory of differential geometry.--Mathoreilly 15:11, 30 June 2008 (EDT)
I also removed the reference to spatial forms, since this belongs in a discussion on Euclidean geometry, and not geometry as a general branch of mathematics.--Mathoreilly 15:13, 30 June 2008 (EDT)
I added geometric measure theory, which is another valid discipline in geometry which is very different from the other branches listed. Additionally, I changed the remark at the beginning about geometry being concerned with points, lines, surfaces, etc., as this is too narrow a description of the field. Finally, the primary branches of pure mathematics are algebra, analysis, and geometry-not algebra and geometry. And it's only fair to include logic and number theory as well, which are enormous subjects with a flavor all their own. In any event, algebra is certainly not the study of numbers--this is number theory. --Mathoreilly 15:28, 30 June 2008 (EDT)

- And while you're at it, please provide references for these definitions. Most students are instructed not to blindly believe things they read on the internet, even here, and wisely so. A reference to a reputable math book or web site will give the student confidence that the information is correct, and may help him find further information is he is so inclined. --Hsmom 09:34, 29 August 2008 (EDT)
Mom, the best website is Wolfram MathWorld. I've never found an error in it.
