Journal ArticleDOI
One loop finiteness of quantum gravity off mass shell
TL;DR: In this paper, the dependence of the counterterms √− gR 2 and √ − gR μν 2 on gauge parameters is calculated in the one-loop approximation in pure quantum gravity.
Journal ArticleDOI
On Possible Generalizations of Field-Antifield Formalism
TL;DR: In this article, a generalized version of the field-antifield formalism is proposed for the first-and second-class antibracket operation, and the quantum master equation and the hypergauge fixing procedure are formulated in a coordinate-invariant way.
Journal ArticleDOI
Reparametrization invariance as gauge symmetry
TL;DR: In this paper, the authors consider the canonical treatment of reparametrization-invariantsystems in which one fixes the gauge on the classical level by means of time-dependent gauge conditions.
Journal ArticleDOI
On the multilevel generalization of the field-antifield formalism
TL;DR: In this paper, a multilevel geometrically covariant generalization of the field-antifield BV formalism is proposed and the structure of quantum generating equations and hypergauge conditions is studied in details.
Journal ArticleDOI
Split involution and second class constraints
TL;DR: In this article, a new quantization scheme was proposed for theories with second class constraints, which possesses properties intermediate between those of the conversion method and quantum deformation of the Dirac bracket.
