Feel free to contact me through this wiki (Talk page, email-relay) about anything here.
French translation of main, information and help pages
in progress here
Waiting for the stabilization of the original english pages.
- Combinatorics, keen on permutations, words and integer partitions.
- Non classical algebras (non-associative systems, quasigroups, near rings and fields,
semigroups, matrices of continuous rank, ...)
- Special functions and their relations to combinatorics and quantum mechanics
- Rational generating functions and series expansions
- French versions of some pages and of some sequences
- Automatization of sequence formatting (with Eric Weisstein)
- Automatization of sequence transforms
- Batches of grid, scales and references sequences
- Mathematica parts of superseeker
- A few Mathematica code for sequences
You can write to me in
- French, English, German
