我们使用陪集超空间构造的另一种形式导出AdS 5 × S5上的Green-Schwarz作用。通过Wick旋转和李代数恒等式,我们将陪集推广到GL(4| 4)/(SP(4)<$GL(1))2,它允许我们表示无约束矩阵上的共形变换。推导过程甚至对于玻色子扇形也更加流线化,并且在每一步都表现出共形对称性。κ-对称规范固定更透明。
We derive the Green-Schwarz action on AdS5 × S5 using an alternate version of the coset superspace construction. By Wick rotations and Lie algebra identifications we bring the coset to GL(4|4)/(SP(4) ⊗GL(1))2, which allows us to represent the conformal transformations on unconstrained matrices. The derivation is more streamlined even for the bosonic sector, and conformal symmetry is manifest at every step. κ-symmetry gauge fixing is more transparent.
