摘要

摘要本文证明了由最小次元生成的双颤振(由3变量轮条件决定)的洗牌代数。结合Varagnolo-Vasserot和Yu Zhao的结果,这表明上述洗牌代数与Grojnowski、Schiffmann-Vasserot和Yang-Zhao的与抖动相关的局域化𝐾-theoretic Hall代数是同构的。稍加修改,我们的定理也适用于等变参数的某些专门化,这将允许我们与Sala和Schiffmann共同工作,给出有限域上任何曲线的霍尔代数的生成和关系描述(这是由于Kapranov-Schiffmann-Vasserot的洗牌代数)。当颤抖器没有边缘环或多条边时,我们证明了shuffle代数、局域𝐾-theoretic Hall代数和对应的量子环群的正半部分都是同构的;得到了Hopf对在后一量子环群上的非简并性。

Shuffle algebras for quivers and wheel conditions
Abstract We show that the shuffle algebra associated to a doubled quiver (determined by 3-variable wheel conditions) is generated by elements of minimal degree. Together with results of Varagnolo–Vasserot and Yu Zhao, this implies that the aforementioned shuffle algebra is isomorphic to the localized 𝐾-theoretic Hall algebra associated to the quiver by Grojnowski, Schiffmann–Vasserot and Yang–Zhao. With small modifications, our theorems also hold under certain specializations of the equivariant parameters, which will allow us in joint work with Sala and Schiffmann to give a generators-and-relations description of the Hall algebra of any curve over a finite field (which is a shuffle algebra due to Kapranov–Schiffmann–Vasserot). When the quiver has no edge loops or multiple edges, we show that the shuffle algebra, localized 𝐾-theoretic Hall algebra, and the positive half of the corresponding quantum loop group are all isomorphic; we also obtain the non-degeneracy of the Hopf pairing on the latter quantum loop group.

期刊介绍: The Journal für die reine und angewandte Mathematik is the oldest mathematics periodical still in existence. Founded in 1826 by August Leopold Crelle and edited by him until his death in 1855, it soon became widely known under the name of Crelle"s Journal. In the almost 180 years of its existence, Crelle"s Journal has developed to an outstanding scholarly periodical with one of the worldwide largest circulations among mathematics journals. It belongs to the very top mathematics periodicals, as listed in ISI"s Journal Citation Report.
