. 建立了单李超代数单参数族D (2 j 1; (cid:16))的特征表达式。我们给出了D (2 j 1; (cid:16))的BGG范畴O中的倾斜模和投影模的Verma (cid:13)ag多重度的完整描述-积分权模,对于任何复参数(cid:16)。然后得到0中所有Verma模块的组成因子。
. We establish character formulae for representations of the one-parameter family of simple Lie superalgebras D (2 j 1; (cid:16) ). We provide a complete description of the Verma (cid:13)ag multiplicities of the tilting modules and the projective modules in the BGG category O of D (2 j 1; (cid:16) )-modules of integral weights, for any complex parameter (cid:16) . The composition factors of all Verma modules in O are then obtained.
