Zekhnini, M. Rezzougui, Mbarrek Haynou, Said Essahel 324 B2 ## Tutorials ## [New features]() ## Tasks - [doctesting]()</br> (Marine, Coline, Paul, Gautier) Finished misc section, and linear algebra section. - [ECPP]() - Use L-function functionality from PARI in Sage; requires a review of current Sage functionality (Jeroen)</br> Tried to replace Lcalc but eventually realized it was not a good idea. - Hyperelliptic curves over finite fields and the rationals (Nicolas)</br> Working on 2-descent. Maybe getting something by the end of the week. - Point counting on elliptic curves and improvements on elliptic curves over finite fields (Jean-Pierre, Cyril, Vincent)</br> Made a patch, already included. - p-adic number field embeddings and regulator (Razvan, Xavier C.)</br> First version of the p-adic regulator. Working for Galois fields, extending to general case. - Coefficients of Hecke eigenforms of half-integral weight and Eisenstein series; doctesting of mf* (Ilker)</br> Worked with Henri, made some good progress using the Rankin-Cohen bracket (mfbracket), found some new examples. - 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)<br/> New name: PariTwine<br/> Autotools support works, detecting the available libraries to wrap<br/> GP script for inclusion of appropriate functions created<br/> Texinfo documentation started (so far, only installation instructions)<br/> Some discussions with Jeroen about code organisation to be compatible with Sage<br/> Next steps: finish documentation, wrap more functions, check the tests<br/> Expected outcome: release 0.1 - Modular forms help centre (Henri)</br> Wrote a bracket function specific to theta to be faster (still slower than magma for silly reasons) - Sato-Tate conjecture (Zakariae)</br> Worked on p-adic regulators and bounds for the p-adic regulator. - Theta functions (Enea) - ECPP (Luca) - p-adic L-functions (Xavier R.) - Algebra package (Aurel) - Infinite order Hecke characters (Aurel, Pascal) Theory and design choice Ok. First GP implem in progress. - Theta series of quadratic forms (Elif)</br> Succeeded to compute in pari/gp with theta functions of binary quadratic forms. Extending to more variables. - SIDH (Cyril)</br> Working on presentation and implementation of SIDH
