Sage Days 38 Coding Sprint Projects
===================================

**For the main Sage Days 38 wiki page go** `here`__.

__ days38

Below is a list of proposed projects.

Combinatorics
-------------

* Sage/`PyCox`_ integration

.. _PyCox: http://arxiv.org/abs/1201.5566

  Nicolas, Meinolf, Franco, Sébastien, Anne, Vivien

* Implementation of the poset of alternating sign matrices (ask Anne Schilling for details)

* class for affine permutations

  Tom, Nicolas, Luis, Chris, Mike, Anne,

* Lambda rings

  Darij

* Diagram algebras

  Stephen, Aaron, George, Nicolas, Darij, Franco, Jim   

* Discrete geometry

  Sébastien, Alexandre, Pierre, 

* clean-up of symmetric functions, k-schur functions, etc.,

  Anne, Chris, Mike, Tom, Luis, Franco,

* improvement of ncsf and qsym; and implement ABS morphism

  Anne, Chris, Mike, Tom, Luis, Franco, Darij, Aaron, Nicolas

* Automorphism group of function fields

  Seyed

* Faster arithmetics in polynomial rings over fraction field of polynomial rings

  Seyed

* semigroups : clean-up, extract good code to push into Sage, ...

  Nicolas, Florent, Anne, Franco, Tom, Travis, 

* rigged configurations

  Travis, Florent and Anne

Representation Theory
---------------------

* Sage interface to QPA_ (`sourceforge page`__)

__ http://www.math.ntnu.no/~oyvinso/QPA/
.. _QPA: http://sourceforge.net/projects/quiverspathalg/

  Franco, Nicolas, Jim, Øyvind, 

* Repn. theory of fin. dim. algebra (ticket #11111)

  Franco, Nicolas, Jim, Øyvind, Florent, 

* fin. dim. cellular algebras

  Stephen, Franco, 

Documentation
-------------

* quick reference card for combinatorics/sage-combinat (see `quickref`_)

* quick reference card for contributing to sage (reviewing patch, cloning a branch, hg commands, ...) (see `quickref`_); most of the content for this exists, it's just a matter of putting it together into the latex document.

* proof-read the combinatorics chapter of the sage book

  Nicolas, Hugh, Timothy

  French version in PDF: Combinatorics chapter in http://sagebook.gforge.inria.fr/

  English version in ReST: http://combinat.sagemath.org/doc/reference/sage/combinat/tutorial.html (upcoming!)

* get tutorials ready for inclusion in Sage

  Nicolas, Franco, ...

Inverse Laplace transform
-------------------------

* Juan Carlos Bustamante

Maxima 3D plot
--------------

* Juan Carlos Bustamante

Find out how to use Maxima to draw 3D plots (using gnuplot for instance).

Implement rotationel and divergence
-----------------------------------

* Juan Carlos Bustamante

Teaching
--------

* WebWork and Sage integration

  Sébastien, Stephen, Malcolm, Alexandra, Vivien, Alexandre, Anne, Franco, Tom
