This page is for listing suggestions for featured content on the Mathematics Portal. If you have suggestions, please feel free to add them here. Also feel free to comment on any suggestions listed here.
For past featured content please see:
Presently, there is no formal process for selecting featured content. This may change if need demands. The maintainers of the portal will select content listed here at their discretion, or, in absence of any suggestions, at their whim.

[edit] Article of the week suggestions
Ackermann function (A-Class)(no image, difficult to give inetresting in limited space avilable)- Derivative (GA)
- Euclidean geometry (GA)
- Nash equilibrium (GA)
- Ordinal number (GA)
- Order theory (GA)
- String theory (GA)
- Sylvester's sequence (GA)
- Znám's problem (GA)
I've also been using Featured articles or articles rated A-Class on the Mathematics articles by quality list, with a bias towards those articles on more obscure areas of maths, and which have a leading picture. I tend to simply copy the introduction and said picture. Tompw 11:09, 17 October 2006 (UTC)
At the time of writing, all FA or A-class maths articles listed at Mathematics articles by quality page have used as AotW, or are on the list to apear. (Two exceptions: Margin of error, where the current image is too detailed to be used at such as small size; and Mathematics, as it's the main article for the portal).

[edit] Upcoming articles
The following is a list of links for the next few weeks, together with the date things change.

- Portal:Mathematics/Featured article/2007_16 (Continuum hypothesis) (16 April)
- Portal:Mathematics/Featured article/2007_17 (23 April)
- Portal:Mathematics/Featured article/2007_18 (30 April)
[edit] Homotopy groups of spheres
I'd like to suggest Homotopy groups of spheres for a article of the week, its been receiving quite a bit of editor attention. E8 (mathematics) might also be worth considering. --Salix alba (talk) 19:24, 21 October 2007 (UTC)

[edit] Did you know... suggestions and current contents
- The DYK box displays a selection of DYK items, which are located at the subpages linked to below.
- The DYK items are transcluded on the main Portal:Mathematics page using {{Did you know|total=12|show=9}}.
- Each day, a new item appears at the top of the list, and the one at the bottom disapears.
- The show parameter is the number of items to be displayed, and cannot be more than 20, nor more than the value of "total".
It should be varied to minimise whitespace in the portal. (This will change according to the size of the Article of the Week and Picture of the Month boxes.) No matter what the value of the show parameter, the first item on the list will be the same. - The total parameter should be the number of subpages (i.e., the toal number of DYK items available).
This should be changed when new DYK items are added (use the redlinks below), and there is no upper limit.
- The show parameter is the number of items to be displayed, and cannot be more than 20, nor more than the value of "total".
- Any problems or further questions, feel free to leave a message on my talk page. Tompw (talk) 12:36, 29 December 2006 (UTC)
List of current DYK items:
- Portal:Mathematics/Did_you_know/1: ...that outstanding mathematician Grigori Perelman was offered a Fields Medal in 2006, in part for his proof of the Poincaré conjecture, which he declined?
- Portal:Mathematics/Did_you_know/2: ...that a regular heptagon is the regular polygon with the fewest number of sides which is not constructible with a compass and straightedge?
- Portal:Mathematics/Did_you_know/3: ...that the Gudermannian function relates the regular trigonometric functions and the hyperbolic trigonometric functions without the use of complex numbers?
- Portal:Mathematics/Did_you_know/4: ...that the Catalan numbers solve a number of problems in combinatorics such as the number of ways to completely parenthesize an algebraic expression with n+1 factors?
- Portal:Mathematics/Did_you_know/5: ...that a sphere can be cut up and reassembled into two spheres the same size as the original (Banach-Tarski paradox)?
- Portal:Mathematics/Did_you_know/6: ...that it is impossible to devise a single formula involving only polynomials and radicals for solving an arbitrary quintic equation?
- Portal:Mathematics/Did_you_know/7: ...that Euler found 59 more amicable numbers while for 2000 years, only 3 pairs had been found before him?
- Portal:Mathematics/Did_you_know/8: ...that you cannot knot strings in 4-dimensions? You can, however, knot 2-dimensional surfaces like spheres.
- Portal:Mathematics/Did_you_know/9: ...that there are 6 unsolved mathematics problems whose solutions will earn you one million US dollars each?
- Portal:Mathematics/Did_you_know/10: ...that there are different sizes of infinite sets in set theory? More precisely, not all infinite cardinal numbers are equal?
- Portal:Mathematics/Did_you_know/11: ...that every natural number can be written as the sum of four squares?
- Portal:Mathematics/Did_you_know/12: ...that the largest known prime is over 9 million digits long?
- Portal:Mathematics/Did_you_know/13: ...that the set of rational numbers is equal in size to the subset of integers; that is, they can be put in one-to-one correspondence?
- Portal:Mathematics/Did_you_know/14: ...that there are precisely six convex regular polytopes in four dimensions? These are analogs of the five Platonic solids known to the ancient Greeks.
- Portal:Mathematics/Did_you_know/15: ...that it is unknown whether π and e are algebraically independent?
- Portal:Mathematics/Did_you_know/16: ...that a nonconvex polygon with three convex vertices is called a pseudotriangle?
- Portal:Mathematics/Did_you_know/17: ...that it is possible for a three dimensional figure to have a finite volume but infinite surface area? An example of this is Gabriel's Horn.
- Portal:Mathematics/Did_you_know/18: ... that as the dimension of a hypersphere tends to infinity, its "volume" (content) tends to 0?
- Portal:Mathematics/Did_you_know/19: ...that the primality of a number can be determined using only a single division using Wilson's Theorem?
- Portal:Mathematics/Did_you_know/20: ...that the line separating the numerator and denominator of a fraction is called a solidus if written as a diagonal line or a vinculum if written as a horizontal line.
