Suggested projects

Bug Squashing

(Michael Abshoff, 1/2 David Harvey, Simon King, Paul Zimmermann)

Polynomial Factory over QQ

(Andy Novocin, Bill Hart, 1/2 David Harvey, Michael Abshoff)

Nash Equlibria

(Greg Bard, Paul Leopardi)

Glucat

(Paul Loepardi)

Linear Algebra over Polynomial Rings

(Burcin Erocal, Arne Storjohann, Clément Pernet)

• (esp. for nullspace computation over fraction fields of these)

Improve the State of Fraction Fields

(Burcin Erocal)

F5

(Martin Albrecht, Michael Brickenstein, Simon King, Ludovic Perret)

• we will read the original F5 paper and try to understand it

• we will port John Perry's F5 Singular and pseudo code to Sage, see: http://www.math.usm.edu/perry/Research/

• additional material: http://eprint.iacr.org/2006/404.pdf

Matrix Factorisation over GF(2)

(Martin Albrecht, Clément Pernet, Greg Bard, Jean-Guillaume Dumas)

• we have many building blocks for LQUP factorization in place in the M4RI library, these need to be plugged together and optimized
• we have two out of four TRSM routines, we need to add the remaining two and optimized the existing ones

Linear Algebra modulo Small Primes

(Clément Pernet, Jean-Guillaume Dumas)

• implement the bound computation and splitting system to use the compressed matmul over small finite fields,
• create a matrix_modn_dense implementation based on floating point coefficients and wrapping most of FFLAS-FFPACK (cf tickets #4258,#4259,#4269)

Sage-Combinat (coming soon)

Linear Algebra on GPU

(Michael Abshoff, Clément Pernet)

• play with the local Ge8800 and FFLAS-FFPACK

Simultaneous Diophantine Approximation of Real Numbers

(Andy Novocin)

non-coding: summarize the entire Sage history for a sagemath.org/library/history.html web-page

(Harald Schilly)

• collect old talks, the documentation, ask someone. You would just have to write text, no html

Add Wrapper for PLURAL to Sage

(Burcin Erocal, Michael Brickenstein)

• see: http://www.singular.uni-kl.de/Manual/3-0-4/sing_355.htm

• see: http://sage.math.washington.edu/home/bricken/plural_2.patch

• Figure out:
  • Where to put these things in the type hierarchy
  • How to create one of these objects
• Progress:
  • general g-algebra creation
  • exterior algebras (seem to) work

Add Better Support for Identifying and Citing "Sub"-Systems

• (Mike Hansen)
• make sure credit goes where credit is due

• There is a initial patch for handling this at http://trac.sagemath.org/sage_trac/ticket/4269

Hilbert class polynomial

(Eduardo Ocampo-Alvarez, Andrey Timofeev)

Implement Sparse FGLM

(Martin Albrecht)

• see http://eprint.iacr.org/2008/402.pdf for timings why this makes sense

Speed-Up Arithmetic for Elliptic Curves over Finite Fields

(Nadia El Mrabet)

French Translation of the Tutorial (A Project for Newcomers!)

(Bertrand Meyer, Marc Mezzarobba)

• as a means to discover Sage while doing something (hopefully) useful, we are trying to translate: http://sage.math.washington.edu/home/mhansen/doc-sphinx/tutorial/

• see http://wiki.sagemath.org/i18n/French

Improve Emacs Interface

(Matthias Meulien)

Work in progress!!! attachment:sage-view.el

attachment:Capture-emacs%40maruta.png

Increase Doctest Coverage

(Paul Zimmermann)

2d Graph Plotting Enhancements

(Emily Kirkman, Philippe Saade)

• The goals include restructuring current graph plot function to have more readable code, as well as adding features such as multiedge plotting and better scaling heuristics. Abandon ship of networkx plotting and interact directly with matplotlib.
