论文摘要
在本文中,我们给出了RTT介绍$ a_ {2n-1}^{(2)} $的扭曲量子仿射代数,并证明它通过L-Operators的高斯分解是对德林菲尔德新实现的同构。这提供了具有非平凡中心元素的扭曲量子仿射代数的第一个此类演示。
In this paper, we give an RTT presentation of the twisted quantum affine algebra of type $A_{2n-1}^{(2)}$ and show that it is isomorphic to the Drinfeld new realization via the Gauss decomposition of the L-operators. This provides the first such presentation for twisted quantum affine algebras with nontrivial central element.
