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.
