Some Wikipedia conventions

Hello. Please look at my recent edits to recurrent tensor. In particular:

• One should not begin an article by saying "Let $\nabla$ be a...". First you need to tell the reader that mathematics is what it's about. Thus: "In mathematics, a recurrent tensor is...." etc.
• Links to connection (mathematics), tensor, manifold, Weyl structure, etc. make it possible for someone not aware that those are standard concepts to find out that they are.
• Generally the introductory section of an article has no heading.
• Typically the first word in a section heading begins with a capital letter; later words begin with a lower-case letter except when there's a reason to capitalize it, e.g. a person's name, etc.
• The same applies to titles of articles. Accordingly, I've changed the title.
• I wouldn't write iff without linking to it. Someone will come along and change it to "if" with an edit summary saying they're correcting the spelling.

Much of this is codified in Wikipedia:Manual of Style and Wikipedia:Manual of Style (mathematics). Michael Hardy (talk) 03:53, 13 January 2010 (UTC)
