我们对非扭仿射李超代数的可积不可约最高权表示进行了分类。在水平1的情况下,我们给出了一个自由域的构造。对这种结构的分析表明,在ℓ(2|1)1级仿射超代数的最简单情况下,特征标用Appell椭圆函数来表示。结果表明,仿射李超代数的表示理论与仿射李代数的表示理论有很大的不同。
We classify integrable irreducible highest weight representations of non-twisted affine Lie superalgebras. We give a free field construction in the level 1 case. The analysis of this construction shows, in particular, that in the simplest case of thesℓ (2|1) level 1 affine superalgebra the characters are expressed in terms of the Appell elliptic function. Our results demonstrate that the representation theory of affine Lie superalgebras is quite different from that of affine Lie algebras.
