Re-parameterization invariance of FRW model: Supervariable and BRST approaches
We perform the Becchi-Rouet-Stora-Tyutin (BRST) quantization of a (0+1)-dimensional cosmological Friedmann-Robertson-Walker (FRW) model. This quantization leverages the classical infinitesimal and continuous re-parameterization symmetry transformations of the system. To derive the nilpotent re-param...
