Website: https://pari.math.u-bordeaux.fr/Events/PARI2027/ Organizers: Bill Allombert Nicolas Billerey Aurel Page This workshop is organized to discuss the current and future development of the PARI/GP system but is open to all arithmeticians with an interest in explicit computations. No previous expertise with PARI/GP is expected, anyone interested is welcome! The workshop will include (1) Short (mathematically oriented) status reports on the current development projects. (2) Tutorial sessions. (3) Brainstorming sessions, to spell out and discuss ideas about the system development: new features, new algorithms, improving old implementations, bug fixes, extensions to GP syntax, documentation overhaul... (4) Hacking sessions: inspired by (3), but also bring your own problems! Please share your ideas for Discussion topics (3) or Coding sessions (4) with the development mailing list . Feel free to suggest topics for the Tutorial sessions (2). REGISTRATION: Please register as soon as possible by sending an email to one of the organizers; participation to the Atelier is free of charge. Five lunches and the conference dinner on Wednesday are offered but we cannot cover travel. Limited funding can be provided to PhD students for local costs: please contact the organisers before October 17th. -- Bill, Nicolas and Aurel
