(Anti-)BRST Symmetries in FLRW Model: Supervariable Approach
Aradhya Shukla, Dharm Veer Singh, R. Kumar
Friedmann-Lemaitre-Robertson-Walker (FLRW) model, representing the isotropic and homogeneous Universe, has an inherent diffeomorphism (or reparametrization) invariance. For a given…

Christ-Lee Model: Augmented Supervariable Approach
R. Kumar, A. Shukla
We derive the complete set of off-shell nilpotent and absolutely anticommuting (anti-)BRST as well as (anti-)co-BRST symmetry transformations for the gauge-invariant Christ-Lee mod…
