Sage Days 5 Working Sprint Projects

Google Video of the Final Status Reports

Put a quick summary here with a link to another page for more details

• NTL wrapper -- do the NTL wrapper right

  • Joel Mohler, Robert Bradshaw, Craig Citro, David Roe, Martin Albrecht, Gonzalo Tornaria, (William Stein)

• Elliptic curves -- basic improvements to elliptic curves

  • Martin Albrecht, David Roe, Dimitar Jetchev, Ifti B., William Stein, Drew Sutherland, Mark Watkins, (Craig Citro, Soroosh Yazdani, Kiran Kedlaya)

• Heegner Points --

  • Matt Greenberg, Dimitar Jetchev, Gonzalo Tornaria (Samit Dasgupta)

• p-Adic Arithmetic -- once again into the breach

  • David Roe, Craig Citro, Kiran Kedlaya, Matt Greenberg, David Harvey (Soroosh Yazdani, Fernando R-V., Abhinav Kumar, Nils Bruin, Amnon Besser, Bill Hart),

• Tensor products, quotients, etc., of free modules -- tensor products and quotients of free modules

  • Soroosh Yazdani, William Stein, Justin Walker, Mike Hansen (remotely)

• Improve the Sage/Magma Interface

  • Nils Bruin, William Stein (if time permits)

• LLL

  • Including wrap Damien's fplll code, finding heuristic for best algorithm to use, benchmarketing, etc.
    • Martin Albrecht, Soroosh Yazdani, Bill Hart (lll heuristic!),

• Coleman integrals and p-adic heights (on Jacobians of genus 2 curves

  • Jennifer Balakrishnan, Amnon Besser, Robert Bradshaw, David Harvey, Kiran Kedlaya, Soroosh Yazdani, Ifti B., (William Stein)

• Divisor arithmetic (Riemann-Roch spaces, linear equivalence) for (plane) curves

  • Nils Bruin (but I need help from someone who knows e.g. Singular: Martin Albrecht), Kiran Kedlaya, (Amnon Besser),

• Coefficient Arithmetic Design ideas about reusing SAGE types in derived SAGE types

  • Joel Mohler, Robert Bradshaw, Craig Citro, David Roe, William Stein, Martin Albrecht, David Harvey

• MatrixWindow_mod2_dense i.e. Strassen for this type

  • Martin Albrecht, David Harvey, Robert Bradshaw (Bill Hart)

• Mod-2 Sparse Linear Algebra

  • - Jason P. gave an F_2 linear algebra program to Bill Hart. Wrap it and put it in Sage and benchmarket it. And thank Jason P.
  • Bill Hart, Martin Albrecht, Michael Abshoff,

• MPolynomial_libsingular over Number Fields This involves writing conversion routines only

  • Martin Albrecht, William Stein, Joel Mohler, Evil Twin.

• Memory Leaks and Valgrind Usage

  • - memory leaks in Cython, dictionaries, ref counts - valgrind
  • Michael Abshoff, Robert Bradshaw, David Harvey, Craig Citro, William Stein, Soroosh Yazdani,
