BRST quantization and equivariant cohomology: localization with asymptotic boundaries [PDF]
Journal of High Energy Physics, 2018 We develop BRST quantization of gauge theories with a soft gauge algebra on spaces with asymptotic boundaries. The asymptotic boundary conditions are imposed on background fields, while quantum fluctuations about these fields are described in terms of ...

Hamiltonian and Lagrangian BRST Quantization in Riemann Manifold [PDF]
Advances in High Energy Physics, 2022 The BRST quantization of particle motion on the hypersurface VN−1 embedded in Euclidean space RN is carried out both in Hamiltonian and Lagrangian formalism. Using Batalin-Fradkin-Fradkina-Tyutin (BFFT) method, the second class constraints obtained using

Hamiltonian and Lagrangian BRST Quantization in Riemann Manifold II [PDF]
Advances in High Energy Physics, 2022 We have previously developed the BRST quantization on the hypersurface VN−1 embedded in N-dimensional Euclidean space RN in both Hamiltonian and Lagrangian formulation.

BRST quantization of cosmological perturbations [PDF]
Journal of Cosmology and Astroparticle Physics, 2016 BRST quantization is an elegant and powerful method to quantize theories with local symmetries. In this article we study the Hamiltonian BRST quantization of cosmological perturbations in a universe dominated by a scalar field, along with the closely ...

Chiral Schwinger model with Faddeevian anomaly and its BRST quantization
European Physical Journal C: Particles and Fields, 2020 We consider chiral Schwinger model with Faddeevian anomaly, and carry out the quantization of both the gauge-invariant and non-invariant version of this model has been.

, 2009 We present the BRST cohomologies of a class of constraint (super) Lie algebras as detour complexes. By giving physical interpretations to the components of detour complexes as gauge invariances, Bianchi identities and equations of motion we obtain a ...

Sp(2)-Symmetric Lagrangian BRST Quantization [PDF]
Nuclear Physics B, 1995 One Lagrangian BRST quantization principle is that of imposing correct Schwinger-Dyson equations through the BRST Ward identities. In this paper we show how to derive the analogous $Sp(2)$-symmetric quantization condition in flat coordinates from an ...

Functional Schroedinger and BRST Quantization of (1+1)--Dimensional Gravity [PDF]
Physical Review D, Particles and fields, 1996 We discuss the quantization of pure string--inspired dilaton--gravity in $(1+1)$--dimensions, and of the same theory coupled to scalar matter. We perform the quantization using the functional Schroedinger and BRST formalisms.

BRST Quantization of Unimodular Gravity [PDF]
Brazilian Journal of Physics, 2015 We study the quantization of two versions of unimodular gravity, namely fully diffeomorphism-invariant unimodular gravity and unimodular gravity with fixed metric determinant, utilizing standard path integral approach.

BRST quantization: A Short review [PDF]
International Journal of Geometric Methods in Modern Physics, 2005 Most of the known models describing the fundamental interactions have a gauge freedom. In the standard path integral, it is necessary to "fix the gauge" in order to avoid integrating over unphysical degrees of freedom. Gauge independence might then become a tricky issue, especially when the structure of the gauge symmetries is intricate.
