Hamiltonian and Lagrangian BRST Quantization in Riemann Manifold
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 The BRST quantization of particle motion on the hypersurface V(N − 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 analysis are converted into first class constraints.

Hamiltonian and Lagrangian BRST Quantization in Riemann Manifold II [PDF]
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 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. We generalize the formalism in the case of L‐dimensional manifold VL embedded in RN with 1 ≤ L < N. The result is essentially the same as the previous one.

Equivariant BRST quantization and reducible symmetries [PDF]
Journal of Physics A: Mathematical and Theoretical, 2006 Working from first principles, quantization of a class of Hamiltonian systems with reducible symmetry is carried out by constructing first the appropriate reduced phase space and then the BRST cohomology.

BRST supergroups and quantization [PDF]
Physics Letters B, 1989 Abstract We construct the smallest supergroup (K) containing among its generators those of a constraint subgroup K, the BRST charge and the corresponding ghost and antighost operators. When K is diffS1 the critical dimension of string theory can be interpreted as a singularity in the carrier space for the irreducible representations of the ...

BRST quantization of a particle in AdS5 [PDF]
Physics Letters B, 1999 We perform the quantization of a massive particle propagating on AdS_5. We use the twistor formulation in which the action can be brought into a quadratic form. We construct the BRST operator which commutes with AdS_5 isometries forming SU(2,2). The condition of a consistent BRST quantization requires that the AdS energy E is quantized in units of the ...

Deformation stability of BRST-quantization [PDF]
AIP Conference Proceedings, 1998 To avoid the problems which are connected with the long distance behavior of perturbative gauge theories we present a local construction of the observables which does not involve the adiabatic limit.

BRST Detour Quantization [PDF]
Journal of Mathematical Physics, 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 ...

On the BPS Sector in AdS3/CFT2 Holography
Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023 Abstract The BPS sector in AdS3/CFT2$AdS_3/CFT_2$ duality has been fertile ground for the exploration of gauge/gravity duality, from the match between black hole entropy and the CFT elliptic genus to the construction of large families of geometrical microstates and the identification of the corresponding states in the CFT.

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory
Fortschritte der Physik, Volume 70, Issue 2-3, March 2022., 2022 Abstract We continue our study of effective field theory via homotopy transfer of L∞$L_\infty$‐algebras, and apply it to tree‐level non‐Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable in mass to the modes that are kept. We focus on the construction of effective actions for string states at fixed
