The complete structure of the WG2 algebra and its BRST quantization
نویسنده
چکیده
The complete structure of the WG2 algebra is obtained from an explicit realization by an abstract Virasoro algebra and a free boson field. We then construct its BRST operator and find a seven-parameter family of nilpotent BRST operators. These free parameters are related to the canonical transformations of the ghost, antighost fields which leave the total stress-energy tensor and the antighost field b invariant.

Quantization of a generally covariant gauge system with two super Hamiltonian constraints
The Becci-Rouet-Stora-Tyutin (BRST) operator quantization of a finitedimensional gauge system featuring two quadratic super Hamiltonian and m linear supermomentum constraints is studied as a model for quantizing generally covariant gauge theories. The proposed model “completely” mimics the constraint algebra of general relativity. The Dirac constraint operators are identified by realizing the B...

In this paper we try to formulate the Berezin quantization on projective Hilbert space P(H) and use its geometric structure to construct a correspondence between a given classical theory and a given quantum theory. It wil be shown that the star product in berezin quantization is equivalent to the Posson bracket on coherent states manifold M, embodded in P(H), and the Berezin method is used to...

The most general quantization prescription available today is provided by the Batalin-Vilkovisky (BV) method[1, 2]. It includes all the results of the BRST method, and also permits a systematic quantization of systems with an open algebra of constraints. Moreover it possesses a rich algebraic structure, that have been considered in the description of String Field Theory [3, 4]. Because of the m...
متن کاملBrst Quantization of Quasi-symplectic Manifolds and Beyond
A class of factorizable Poisson brackets is studied which includes almost all reasonable Poisson manifolds. In the simplest case these brackets can be associated with symplectic Lie algebroids (or, in another terminology, with triangular Lie bialgebroids associated to a nondegenerate r-matrix). The BRST theory is applied to describe the geometry underlying these brackets and to develop a covari...
