双分划量子簇代数

Double-partition Quantum Cluster Algebras

Hans Plesner Jakobsen, Hechun Zhang

摘要:

引入并研究了一类量子团簇代数。在一般情况下,这些代数是新的,但子类已经研究了以前的其他作者。这些代数是由双划分或双旗簇索引的。等效地,它们由折线$L$索引。通过将相邻的突变组合成量子线突变,我们可以从一条折线的簇代数突变到另一条。兼容对可以写下来。这些代数等于它们的上簇代数。量子种子的变量由对偶正则基的元素给出。这是最终版本,其中一些论点已经扩大和/或改进,并纠正了几个错别字。完整的书目细节:代数杂志(2012年),pp。172-203 DOI信息:10.1016/j.jalgebra.2012.09.015

英文摘要:

A family of quantum cluster algebras is introduced and studied. In general, these algebras are new, but subclasses have been studied previously by other authors. The algebras are indexed by double partitions or double flag varieties. Equivalently, they are indexed by broken lines $L$. By grouping together neighboring mutations into quantum line mutations we can mutate from the cluster algebra of one broken line to another. Compatible pairs can be written down. The algebras are equal to their upper cluster algebras. The variables of the quantum seeds are given by elements of the dual canonical basis. This is the final version, where some arguments have been expanded and/or improved and several typos corrected.
