Sp(2)-Symmetric Lagrangian BRST Quantization

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 co...

From Hamiltonian to Lagrangian Sp(2) BRST Quantization

We give a formal proof of the equivalence of Hamiltonian and Lagrangian BRST quantization. This is done for a generic $Sp(2)$-symmetric theory using flat (Darboux) coordinates. A new quantum master equation is derived in a Hamiltoni...

Superfield Quantization

We present a superfield formulation of the quantization program for theories with first class constraints. An exact operator formulation is given, and we show how to set up a phase-space path integral entirely in terms of superfields. BR...

Reducible Gauge Algebra of BRST-Invariant Constraints

algebra of the operator formalism by only using BRST-invariant constraints anticommuting BRST operators that bear structural similarities with BRST/anti-BRST theories but with shifted ghost number assignments. In ...

BRST Formulation of Partition Function Constraints

We show that constraints on the generating functional have direct BRST-extensions in terms of nilpotent operators $Delta$ that annihilate this generating functional, and which may be of arbitrarily high order. The free energy $F$ in the pres...

BRST cohomology of timelike Liouville theory

We compute the Hermitian sector of the relative BRST cohomology of the spacelike and timelike Liouville theories with generic real central charge cL_{L}L​ in each case, coupled to a spacelike Coulomb gas and a generic transverse CFT our form...

Quantization of the particle with a linear massless solution

In this work, a solution linear in the momentum for the massless constraint PmPm = 0 is investigated. It is presented in terms of a SO(2n, ℂ) to U(n) decomposition and interpreted in terms of projective pure spinors, which are known to parametrize th...

Algebra of Higher Antibrackets

We present a simplified description of higher antibrackets, generalizations of the conventional antibracket of the Batalin-Vilkovisky formalism. We show that these higher antibrackets satisfy relations that are identical to those of higher string pro...

Geometry of the Batalin-Fradkin-Vilkovisky Theorem

We describe gauge-fixing at the level of virtual paths in the path integral as a non-symplectic BRST-type of flow on the path phase space. As a consequence a gauge-fixed, non-local symplectic structure arises. Restoring of locality is discus...
