Level-rank dualities and moving vectors
Wei Hu, Feiyue Huang, Yanbo Li +1
Duality relations between Lie algebras are a significant phenomenon in Lie algebra representation theory, with level-rank duality as a famous example. Level-rank dualities for affi…

Moving vectors and core blocks of Ariki-Koike algebras
Yanbo Li, Xiangyu Qi, Kai Meng Tan
We classify the core blocks of Ariki-Koike algebras by their moving vectors. Using this classification, we obtain a necessary and sufficient condition for Scopes equivalence betwee…

Cores and weights of multipartitions and blocks of Ariki-Koike algebras
Yanbo Li, Kai Meng Tan
Let be an integer at least two. We define the -core and the -weight of a multipartition associated with a multicharge as the -core and the -weight of its image unde…
