我们得到Ariki-Koike代数的一个块具有以下性质的充要条件：其所有相关的多划分都没有给定剩余的可加节点。这根据金字塔数和Scopes向量对Ariki-Koike代数的Scopes等价类进行了分类，推广了1级和核心块的分类。我们的证明独立于Richards关于1级的结果。
英文摘要
We obtain necessary and sufficient conditions for a block of an Ariki-Koike algebra to have the property that all its associated multipartitions have no addable node with a given residue. This leads to a classification of Scopes equivalence classes for Ariki-Koike algebras in terms of their pyramid numbers and Scopes vectors, generalising that for level 1 and for core blocks. Our proof is independent of the results of Richards for level 1.
