空弦是无质量粒子的模拟，即张力为零或斜率无限大的弦。我们提出了空玻色弦约束代数的超对称扩展，并且为了协变量化，构造了相应的 BRST 电荷。我们发现零超对称（玻色）弦仅在 D = 10 (D = 26) 时才是量子一致的。仅在与切线方向相关的单个 Virasoro 子代数中生成异常。
Null strings are the analog of massless particles, namely strings with zero tension or infinite slope. We present the supersymmetric extension of the null bosonic string constraint algebra and, in order to quantize covariantly, construct the corresponding BRST charge. We find that the null supersymmetric (bosonic) string is quantum consistent only in D = 10 (D = 26). The anomalies are generated only in the single Virasoro subalgebra associated to the tangenial direction.
