GL(2)和SL(1/2)双参数形变的Drinfeld扭曲

Drinfeld twist for two-parametric deformation of gl(2) and sl(1/2)

N. Aizawa

摘要:

对李代数gl(2)进行Drinfeld扭曲,得到了gl(2)的双参数变形,这与Aneva等人得到的gl(2)的Jordan变形相同.由于gl(2)嵌入sl(1/2)中,所以对李超代数sl(1/2)也采用了同样的扭曲元.利用FRT形式主义,我们构造了李超群$ SL(1/2). $的变形

英文摘要:

Drinfeld twist is applied to the Lie algebra gl(2) so that a two-parametric deformation of it is obtained, which is identical to the Jordanian deformation of the gl(2) obtained by Aneva et al. The same twist element is applied to deform the Lie superalgebra sl(1/2), since the gl(2) is embedded into the sl(1/2). By making use of the FRT-formalism, we construct a deformation of the Lie supergroup $ SL(1/2). $
