离散全纯性与量子仿射代数

Discrete holomorphicity and quantized affine algebras

Y. Ikhlef, R. Weston, M. Wheeler, P. Zinn-Justin

摘要:

我们认为非本地电流的背景下,量子化仿射代数,以下介绍的建设伯纳德和费尔德。在$U_q(A_1^{(1)})$和$U_q(A_2^{(2)})$的情况下,这些电流可以与六顶点和Izergin-Korepin十九顶点模型中的配置相识别。映射到相应的Temperley-Lieb回路模型,我们直接识别非本地电流离散全纯回路可观。特别是,我们表明,散装离散的全纯关系和最近派生的边界模拟相当于非本地电流的守恒律。

英文摘要:

We consider non-local currents in the context of quantized affine algebras, following the construction introduced by Bernard and Felder. In the case of $U_q(A_1^{(1)})$ and $U_q(A_2^{(2)})$, these currents can be identified with configurations in the six-vertex and Izergin--Korepin nineteen-vertex models. Mapping these to their corresponding Temperley--Lieb loop models, we directly identify non-local currents with discretely holomorphic loop observables. In particular, we show that the bulk discrete holomorphicity relation and its recently derived boundary analogue are equivalent to conservation laws for non-local currents.
