# [Welcome to Atelier PARI/GP 2020 (Grenoble)](http://pari.math.u-bordeaux.fr/Events/PARI2020/)
## Tasks
- [doctesting](doc2020) (Marine, Valentin, Mohamed, Cyril, Razvan, Anne-Edgar, Samuele, Baptiste, Julien, Paul) (many reports, some already incorporated)
- Philippe (pari tutorial for teachers: arithmetics, algebra etc)
- Xavier (p-adic L-functions) (debugging)
- Jared (morphisms between finite abelian groups) (discussions with KB and 
  Andreas about abelian groups)
- Andreas (modular polynomials) (computed a modular polynomial, discussed CM theory and groups)
- Karim (supervise doctesting, help everyone)
- Henri (help people)
- Roland (parallel computing) (linking pari and GPUs with cypari; quite hard!)
- Francesco (enumeration of number fields with prescribed ramification) (trying to use some congruences for quintics)
- Aurel (Hecke characters, p-adic fields) (found and fixed bugs)
- Titouan (elliptic curves) (work on a benchmark)
- Maiga (hyperelliptic curves, elliptic curves) (tests with invariants)
- Razvan (mf, modular poly) (computed a modular polynomial with Andreas, finishing slides)
- Denys (parallel computing) (working with Vinko)
- Samuele (modular forms, modular symbols, isomorphism of Galois representations) (talked to people)
- Nicolas (congruences between modular forms, mfsearch) (learning how to make patches)
- Baptiste (modular forms) (working on the small image project, talk)
- Etienne (LLL over number fields) (cleaned up quadratic case, slides)
- Christelle (exploration of pari) (root localisation, extending to special types of polynomials)
- Vinko (computations with factorisations) (trying parallel programming)
- Richard (discover pari, elliptic curves over function fields) (<- did this)
- Julien (discover pari, number fields) (slacking off)
- Francois (compute Eisenstein series, products of such) (<- worked on this)
- Bernadette (modular symbols) (worked with Francois)
- Pascal (Hecke characters) (worked with Aurel)
