Bruce W. Westbury, Paul Zinn-Justin

AI总结:

针对射影线上每个点对应单李代数的例外系列,在L⊕I表示中构造统一三角R矩阵,通过16维与287维插值代数实现其杨-巴克斯特方程性质,覆盖含五个例外李代数的系列。

摘要:

例外系列是射影线上的有限点列表,每个点对应一个单李代数,其中包含五个例外李代数。我们在表示L⊕I中给出例外系列的统一三角R矩阵,L是伴随表示的量子形变,I是平凡表示。我们构造了16维代数A□(2)(插值End(⊗²(L⊕I)))和287维代数A□(3)(插值End(⊗³(L⊕I)))。该R矩阵属于A□(2)且满足A□(3)中的杨-巴克斯特方程,可插值例外系列各点的三角R矩阵。

英文摘要:

The exceptional series is a finite list of points on a projective line with a simple Lie algebra attached to each point. This list of Lie algebras includes the five exceptional Lie algebras. We give a uniform trigonometric $R$-matrix for the exceptional series in the representation $L\oplus I$, where $L$ is the quantum deformation of the adjoint representation and $I$ is the trivial representation. We construct a sixteen dimensional algebra, $A^\square(\mathit2)$, which interpolates the algebras $\mathrm{End}(\otimes^2(L\oplus I))$ and a 287 dimensional algebra, $A^\square(\mathit3)$, which interpolates the algebras $\mathrm{End}(\otimes^3(L\oplus I))$. The $R$-matrix lives in $A^\square(\mathit2)$ and satisfies the Yang-Baxter equation in $A^\square(\mathit3)$; it interpolates the trigonometric $R$-matrices for the points in the exceptional series.
