Tasks

• doctesting

• ECPP

• Use L-function functionality from PARI in Sage; requires a review of current Sage functionality (Jeroen)

• Hyperelliptic curves over finite fields and the rationals (Nicolas)

• Point counting on elliptic curves and improvements on elliptic curves over finite fields (Jean-Pierre, Cyril, Vincent)

• p-adic number field embeddings and regulator (Razvan, Xavier C.)

• Coefficients of Hecke eigenforms of half-integral weight and Eisenstein series; doctesting of mf* (Ilker)

• Little delta function by Zagier (Zeynep)

• Dedekind eta function (Banu)

• Modular forms and symbols (François, Bernadette)

• Improve PARI-GNUMP (Andreas, Fredrik) and maybe use it in SageMath? (Jeroen) New name: PariTwine Autotools support works, detecting the available libraries to wrap GP script for inclusion of appropriate functions created Texinfo documentation started (so far, only installation instructions) Some discussions with Jeroen about code organisation to be compatible with Sage Next steps: finish documentation, wrap more functions, check the tests Expected outcome: release 0.1

• Modular forms help centre (Henri)

• Sato-Tate conjecture (Zakariae)

• Theta functions (Enea)

• ECPP (Luca)

• p-adic L-functions (Xavier R.)

• Algebra package (Aurel)

• Infinite order Hecke characters (Aurel, Pascal)

• Improve PARI-GNUMP (Andreas, Fredrik) and maybe use it in SageMath? (Jeroen)

• Theta series of quadratic forms (Elif)
