两个边界Temperley-Lieb代数的校准表示

Calibrated representations of two boundary Temperley-Lieb algebras

Zajj Daugherty, Arun Ram

摘要:

双边界Temperley-Lieb代数$TL_k$起源于统计力学中格点模型的传递矩阵公式,特别是在六顶点模型中引入可积边界项。在本文中,我们分类和研究的校准表示-那些所有的墨菲元素(积分)是同时对角化-这反过来又对应于对角化的相关模型中的传递矩阵。我们的方法是建立在实现$TL_k$作为一个商的类型$C_k$仿射Hecke代数$H_k$。在以前的工作中,我们研究了这个Hecke代数,通过它的表现形式的辫子图,张量空间运营商,和相关的组合结构。这项工作直接应用于本文给出了一个组合分类和建设的所有不可约校准$TL_k$ -模块,并解释如何这些模块也出现从舒尔-外尔对偶与量子群$U_q\mathfrak{gl}_2$。

英文摘要:

The two boundary Temperley-Lieb algebra $TL_k$ arises in the transfer matrix formulation of lattice models in Statistical Mechanics, in particular in the introduction of integrable boundary terms to the six-vertex model. In this paper, we classify and study the calibrated representations---those for which all the Murphy elements (integrals) are simultaneously diagonalizable---which, in turn, corresponds to diagonalizing the transfer matrix in the associated model. Our approach is founded upon the realization of $TL_k$ as a quotient of the type $C_k$ affine Hecke algebra $H_k$. In previous work, we studied this Hecke algebra via its presentation by braid diagrams, tensor space operators, and related combinatorial constructions. That work is directly applied herein to give a combinatorial classification and construction of all irreducible calibrated $TL_k$-modules and explain how these modules also arise from a Schur-Weyl duality with the quantum group $U_q\mathfrak{gl}_2$.
