Projects

1. Update Owen and Jeff's Genus Code.
   • Emily Kirkman

     • Use the current [http://sage.math.washington.edu:8500/genus_code version].

     • Inclusion of [http://pigale.sourceforge.net/ PIGALE] should lead to an improvement here as well (see below).

2. Algorithm to test for recoverability
   • Emily Kirkman
   • Circular Planarity Testing:
     • Status: Linear time achievable by modifying the graph before calling an O(n) planar embedding (testing) algorithm. (Not reinventing the wheel, just sticking one in the graph). Currently working on including the Boost library in SAGE.
     • Resources:

       • A simple O(n) Planarity Testing [http://www.cs.uvic.ca/~wendym/my_pubs/boyer.ps Algorithm]

       • [http://boost.sourceforge.net/ Boost] implementation of the algorithm.

   • Criticality
3. Enhancing precision with exact linear algebra
   • Tom Boothby, Emily Kirkman
4. Combinatorics of Coxeter Groups (with Sara Billey)
   • Tom Boothby, Sean Howe, Emily Kirkman, Robert Miller
   • [:reu07/bruhat_notes]
5. Dirichlet Problem for Directed Networks
   • Kari Christianson, Lindsay Erickson
6. Star-Ks and 2:1 Networks w/ Complex Admittance
   • Lindsay Erickson
7. Graphs and Connections on a Surface of Arbitrary Genus
   • Joe Mitchell
8. Angle Systems and Embeddings
   • Joey Greer, Emily Kirkman
9. New Algorithm for Finding Planar Embeddings with user-defined Topological Constraints
   • Emily Kirkman

10. [:Leon:Update] Jeffrey Leon's Partition Backtracking code

    • Tom Boothby, Robert Miller

Wiki examples

To include a link:

[http://www.math.washington.edu/~morrow/reu07/reu.html Jim Morrow's page]
[:Leon: update]

To add a table of contents:

[[TableOfContents]]

To format the table of contents (simultaneously formatting the page):

== Top Level, No. 1 ==
== Top Level, No. 2 ==
=== Next Level, No. 1 ===
=== Next Level, No. 2 ===
==== Another Level, etc. ====
== Top Level, No. 3 ==

To create a new wiki page, simply navigate there, and you will be given a new blank page.

MoinMoin, this particular brand of wiki, also allows you to use LaTeX:

\sum_{k=1}^n{n \choose k}x^k

Here's how to do that:

$$\sum_{k=1}^n{n \choose k}x^k$$
$\sum_{k=1}^n{n \choose k}x^k$
$$\left[\begin{array}{cccc}1 & 0 & 0 & 0 \\0 & 1 & 0 & 0 \\0 & 0 & 0 & \omega \\0 & 0 & -\omega & 0\end{array}\right]$$

NOTE: The double-dollar notation is a replacement for LaTeX's math environment \[...\], which does not work in the wiki.
