Workgroups are no longer used for group communications, but they still are used to group articles into fields of interest. Each article is assigned to 1-3 Workgroups via the article's Metadata. |

Work plan white paper
The topics below are part of the division of mathematical knowledge to subdisciplines; 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 other workgroups (usually the physicists) to do the work alongside - we state where.
Caveats:
- Do not copy articles from Wikipedia without carefully reading them, verifying both scope and focus. Besides, why not consider writing your article from scratch? Often this permits a better logical structure and more coherence. See CZ:How to convert Wikipedia articles to Citizendium articles
- Keep in mind three audiences when writing an article: general readers, math students and professionals.
Most wanted math entries
From the encyclopedic point of view, the "high priority" articles are probably listed below at the top level of the tree (or in the table of contents). These are, however, relatively wide syntheses. You may want to start with a bit smaller tasks. A collection of important entries to write (of both types) can be found on the Core Articles page (still to be reviewed and reorganized).
Most popular Wikipedia math entries are: Pi, Mathematics , prime number, computer, trapezoid. These come from the list of 1000 most viewed pages in March 2007.[3] This varies heavily over the time.
On Planet Math, the most popular (as of March 2007) were:[4] circle, proof of Markov's inequality, Cauchy-Schwarz inequality, matrix inverse, Banach fixed point theorem, metric space, invariant subspace, function, manifold, eigenvalue, quartic formula, Jensen's inequality, cross product, real number, differential equation, gradient, natural number, Jacobian matrix, Gram-Schmidt orthogonalization, rational number.
