Work plan white paper

The topics below are part of the division of mathematical knowledge to subdiciplines; they come from the 2000 Math. subject classification of the AMS [1] and ZMATH [2], with some minor edits. Each of these top level topics is a big subject, and it is not necessarily our first priority to write a long article on these entries. Our object with outlining this list is to establish a framework. We recommend that when you write a new article, you should try to find a proper node for it. Do not hesitate to put a link for an article you want to work on soon. Feel free to do the same to request a particular important topic to be covered.

Remarks:

• We kept the original MSC numbering in places.
• No, of course its not the whole MSC tree - not even close to it. We should eventually put as much of it as appropriate.
• In some places we really expect some otherwork group (usually the physicsits) to do the work for us - we state where.

Caveats:

• Do not copy articles from wikipedia without carefully reading them, verifying both scope and focus. See Citizendium Pilot:How to convert Wikipedia articles to Citizendium articles
• Keep in mind three audiences when writing an article: general readers, math students and professionals.
