稳定极限的A型非对称Macdonald函数

Stable-Limit Non-symmetric Macdonald Functions in Type A

Milo Bechtloff Weising

摘要:

构造并研究了极限Cherednik算子$\mathscr{Y}_i$的$^+$稳定极限双仿射Hecke代数的Ion和Wu标准表示的显式同时$\mathscr{Y}$特征基.这个基础作为$GL_n$型的切雷德尼克非对称麦克唐纳多项式的推广而出现。我们利用之间的联系$^+$稳定极限双仿射Hecke代数理论的离子和吴和双Dyck路径代数的卡尔森和Mellit,出现在他们的证明洗牌猜想。作为结果,谱理论的限制Cherednik运营商的理解。

英文摘要:

We construct and study an explicit simultaneous $\mathscr{Y}$ eigenbasis of Ion and Wu's standard representation of the $^+$stable-limit double affine Hecke algebra for the limit Cherednik operators $\mathscr{Y}_i$. This basis arises as a generalization of Cherednik's non-symmetric Macdonald polynomials of type $GL_n$. We utilize links between $^+$stable-limit double affine Hecke algebra theory of Ion and Wu and the double Dyck path algebra of Carlsson and Mellit that arose in their proof of the Shuffle Conjecture. As a consequence, the spectral theory for the limit Cherednik operators is understood.
