量子群及其晶体基的子群范畴方法

量子代数 2019-12-09 v1

摘要

设我们有一个半单、连通、单连通代数群 GG,其对应李代数为 g\mathfrak{g}。在泛包络代数 U(g)U(\mathfrak{g}) 与坐标环 O(G)O(G) 之间存在一个 Hopf 配对。通过引入参数 qq,我们可分别考虑量子形变 Uq(g)U_q(\mathfrak{g})Oq(G)O_q(G),它们之间再次存在 Hopf 配对。我们证明与 Uq(g)U_q(\mathfrak{g}) 相关的晶体范畴是一个幺半群范畴。我们将 Uq(g)U_q(\mathfrak{g}) 的子群定义为右余理想子代数,将 Oq(G)O_q(G) 的子群定义为商左 Oq(G)O_q(G)-模余代数。此外,我们讨论量子群子群的范畴方法,希望借此提供与晶体基理论的联系。
