计算了10维、11维和12维纯旋量空间上全纯函数的特征。从这个特征公式,我们以明显协变的方式导出了超弦的纯旋量形式中出现的各种中心荷。对于D=10和D=11的超粒子,我们还简单地导出了纯旋量BRST算符的零动量上同调
The character of holomorphic functions on the space of pure spinors in 10, 11 and 12 dimensions is calculated. From this character formula, we derive in a manifestly covariant way various central charges which appear in the pure spinor formalism for the superstring. We also derive in a simple way the zero momentum cohomology of the pure spinor BRST operator for the D=10 and D=11 superparticle
