论文摘要
我们阐述了$ \ mathsf {cp^{n-1}} $ sigma模型的表述，并将其作为测量的gross-neveu模型。这种方法允许将模型的超级空间识别为超透明质商。潜在的手性量表异常显示可从玻色子和费米子接收贡献，并且与该相空间的性质有关。在此过程中，我们证明了世界表超对称模型是具有目标空间超对称性模型的超完整商。简要讨论了对其他箭袋的概括。
We elaborate the formulation of the $\mathsf{CP^{n-1}}$ sigma model with fermions as a gauged Gross-Neveu model. This approach allows to identify the super phase space of the model as a supersymplectic quotient. Potential chiral gauge anomalies are shown to receive contributions from bosons and fermions alike and are related to properties of this phase space. Along the way we demonstrate that the worldsheet supersymmetric model is a supersymplectic quotient of a model with target space supersymmetry. Possible generalizations to other quiver supervarieties are briefly discussed.
