Goblins for number theory

I am working on a series of blog posts on how to use the Spritely Goblins approach of distributed computation for the kind of embarrassing parallelisation I encounter in algorithmic number theory, with the aim of potentially replacing the use of MPI. Making this announcement, I am assuming the risk of a series that may finally be so short as to not merit the name, in particular, since I am writing the text up as I try to work through the problem and do not know the eventual outcome yet.

2. Parallel Goblins
3. Ending and persisting
4. Client and server Goblins

Conférence de cryptologie pour des collégienꞏnes et lycéenꞏnes

Crypto (in French), March 2025; this is the support for a presentation made for pupils between 11 (by accident, the target audience was above 14!) and 17 years old.

Videos

Presentation of the CANARI team by some of its members. A shortened version is also available.

Ten Years of Failures, talk at the 10 Years of Guix event.

École d'été à Douala

J'ai donné un cours sur la théorie algorithmique des nombres à l'école CIMPA Algèbre, géométrie algébrique et applications à la théorie de l'information. Mes notes de cours vont un peu plus loin que ce que j'ai réellement fait en classe. Quelques démonstrations omises peuvent être trouvées dans le livre de Neal Koblitz, A Course in Number Theory and Cryptography, 1994.

Conferences

ECC 2015 took place in Bordeaux.

DJ 60, the conference in honour of Dieter Jungnickel's 60th birthday, took place in Magdeburg in 2012.

Publishing

Some time ago, I signed the boycott of working for Elsevier, see Timothy Gowers's blog post. It has saved me a bit of work, but not that much actually; luckily we have a very healthy ecosystem of mathematical journals that are published by learnt societies and not-for-profit organisations.
