Identifying Young diagrams among residue multisets
AI总结:
本文研究给定剩余多重集是否源自杨图的逆问题,利用Fayers概念在层一给出完整解答,并应用于划分的移位操作。
摘要:
对于任意杨图,我们可以关联其所有节点的剩余类多重集。本文关注逆问题:给定一个Z/eZ元素的多重集,它是否来自某个杨图?我们利用Fayers关于多重划分的核心块和权重的概念,在层一给出了完整解答,并在更高层对杨多重图给出了部分答案。我们将层一的结果应用于研究划分上的移位操作。
英文摘要:
To any Young diagram we can associate the multiset of residues of all its nodes. This paper is concerned with the inverse problem: given a multiset of elements of Z/eZ, does it comes from a Young diagram? We give a full solution in level one and a partial answer in higher levels for Young multidiagrams, using Fayers's notions of core block and weight of a multipartition. We apply the result in level one to study a shift operation on partitions.
