Core abaci and Diophantine equations I: fundamental weight
Yanbo Li, Jiansheng Zhang, Shasha Zhu
In the light of a series of papers on moving vectors, we define and study core abaci of classical affine types for arbitrary charge. This greatly extends the concept of cores with…

Moving vectors I: Representation type of blocks of Ariki-Koike algebras
Yanbo Li, Xiangyu Qi
We introduce a new invariant for blocks of Ariki-Koike algebras, called block moving vector, which is a vector of non-negative integers summing up to the weight of the block. In th…
