论文摘要
我们讨论了宇宙学的Friedmann-Robertson-Walker（FRW）模型的脱壳nilpotent becchi-rouet-stora-tyutin（BRST）和反对对称性转换。在此讨论中，反对对称性的存在提供了对可超级方法的范围内BRST的完整几何描述。我们使用著名的Noether定理得出了FRW模型的保守（反）BR，并显示了这些保守的指控在BRST形式主义领域内的nil弱和绝对反交换性能。最后，我们通过在（反）手性监督方法（ACSA）的框架内推导这些对称性转换来证明（反）BRST对称性的神圣性。
We discuss both the off-shell nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for the cosmological Friedmann-Robertson-Walker (FRW) model with a differential gauge condition in the extended phase space. In this discussion, the presence of anti-BRST symmetry provides the complete geometrical description of BRST within the ambit of the supervariable approach. We derive the conserved (anti-)BRST charges for the FRW model using the celebrated Noether theorem and show the nilpotency and absolute anti-commutativity properties of these conserved charges within the realm of BRST formalism. Finally, we prove the sanctity of (anti-)BRST symmetries through the derivation of these symmetry transformations within the framework of the (anti-)chiral supervariable approach (ACSA) to BRST formalism.
