International Journal of Modern Physics A, 1991
After a brief review of the BRST formalism and of the Parisi-Wu stochastic-quantization method, the BRST-stochastic-quantization scheme is introduced. This scheme allows the second quantization of constrained Hamiltonian systems in a manifestly gauge-symmetry-preserving way.

BRST-quantization and unitarity
Nuclear Physics B - Proceedings Supplements, 1990Abstract Unitarity conditions for indefinite metric field theories are formulated. Using these conditions a new approach to the BRST-quantization is developed. Some applications are discussed.

On the macroscopic level, Einstein’s general relativity (GR) has passed every test “with flying colors”; see Will (2006, 2014) for recent reviews. However, Einstein’s theory has thus far resisted every attempt at quantization, e.g., it is known to be perturbatively nonrenormalizable, partially due to its dimensional coupling constant.

THE BRST AND ANTI-BRST INVARIANT QUANTIZATION OF GENERAL GAUGE THEORIES
Modern Physics Letters A, 1990The Batalin-Vilkovisky procedure for the BRST invariant path-integral quantization of general gauge theories is discussed. An extension of this is given in which a path integral is constructed that is invariant under an anti-BRST symmetry as well as the BRST symmetry.

BRST-QUANTIZATION OF BOSONIC STRINGS AND HYPERTWISTORS
Modern Physics Letters A, 1990We consider the relation between geometric quantization of bosonic strings and the Becchi-Rouet-Stora-Tyutin (BRST) approach. We introduce the space of hypertwistors as the total space of the bundle of complex structures over the phase space of bosonic string.

BRST quantization of topological field theory
Physical Review D, 1990Summary: The canonical quantization of the topological field theory model \(\int_M F\wedge B\), proposed by Horowitz, is examined through the Becchi-Rouet-Stora-Tyutin approach. With this approach we have a manifestly covariant description of a certain class of topological quantum field theories. However, if \(M\) in the present model is any orientable

BRST quantization and coadjoint orbit theories
Physical Review D, 1991A new ‘harmonic’ BRST method is presented for quantizing those dynamical systems having second-class constraints which split into holomorphic and antiholomorphic algebras. These theories include those whose phase spaces are coadjoint orbits of a compact semisimple Lie group.

BRST QUANTIZATION OF GAUGE THEORIES ON THE HYPERSPHERE
Modern Physics Letters A, 1991Drummond and Shore have shown that the most convenient gauge fixing term for gauge theories on a hypersphere is not a perfect square. We show how BRST quantization can be used to generate this gauge fixing term. This involves the introduction of two ghost fields, ci and [Formula: see text], the second of which is an anticommuting vector field.
