چکیده
We discuss both the off-shell nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for cosmological Friedmann-Robertson-Walker (FRW) model with a differential gauge condition in extended phase space. In this discussion, presence of provides complete geometrical description BRST within ambit supervariable approach. derive conserved (anti-)BRST charges FRW using celebrated Noether theorem show nilpotency absolute anti-commutativity properties these realm formalism. Finally, we prove sanctity symmetries through derivation framework (anti-)chiral approach (ACSA) to

A Friedmann - Lemâıtre - Robertson - Walker cosmological model with running Λ
The idea of a variable dark energy has been entertained many times in the literature and from many different points of view. Quintessence is just a popular way to implement this idea in recent times, but so far with little success. Another possibility is to think of the cosmological term, Λ, as a “running quantity” much in the same way as the electromagnetic coupling constant. However, the fact...
متن کاملFriedmann-robertson-walker Cosmologies
Abstract. Electrodynamics for self-interacting scalar fields in spatially flat FriedmannRobertson-Walker space-times is studied. The corresponding one-loop field equation for the expectation value of the complex scalar field in the conformal vacuum is derived. For exponentially expanding universes, the equations for the Bogoliubov coefficients describing the coupling of the scalar field to grav...
متن کاملFriedmann-lemaˆıtre-robertson-walker Cosmology
Distance–redshift relations are given in terms of associated Legendre functions for partially filled beam observations in spatially flat Friedmann-Lemaˆıtre-Robertson-Walker (FLRW) cosmologies. These models are dynamically pressure-free, flat FLRW on large scales but, due to mass inhomogeneities, differ in their optical properties. The partially filled beam area-redshift equation is a Lame ′ eq...
متن کاملChaotic Friedmann - Robertson - Walker Cosmology
We show that the dynamics of a spatially closed Friedmann Robertson Walker Universe conformally coupled to a real, free, massive scalar field, is chaotic, for large enough field amplitudes. We do so by proving that this system is integrable under the adiabatic approximation, but that the corresponding KAM tori break up when non adiabatic terms are considered. This finding is confirmed by numeri...
متن کاملThe Hamiltonian of Asymptotically Friedmann-Lemâıtre-Robertson-Walker Spacetimes
We obtain the correct hamiltonian which describes the dynamics of classes of asymptotic open Friedmann-Lemâıtre-Robertson-Walker (FLRW) spacetimes, which includes Tolman geometries. We calculate the surface term that has to be added to the usual hamiltonian of General Relativity in order to obtain an improved hamiltonian with well defined functional derivatives. For asymptotic flat FLRW spaces,...
