Cores of Ariki-Koike algebras
Résumé
We study a natural generalization of the notion of cores for l-partitions attached with a multi-charge s ∈ Z^l : the (e, s)-cores. We rely them both to the combinatorics and the notion of weight defined by Fayers. Next we study applications in the context of the block theory for Ariki-Koike algebras.
