Subalgebras of the Gerstenhaber algebra of differential operators
A. V. Bratchikov
We construct a family of subalgebras of the Gerstenhaber algebra of differential operators. The subalgebras are labeled by subsets of the additive group that are cl…
Classical BRST charges in reducible BRST-anti-BRST theories
A. V. Bratchikov
We give a solution to the classical master equation of the Hamiltonian BRST-anti-BRST quantization scheme in the case of reducible gauge theories. Our approach does not require red…
Gauge algebra of irreducible theories in the Sp(2)-symmetric BRST formalism
A. V. Bratchikov
An explicit solution to classical master equations of the Sp(2)-symmetric Hamiltonian BRST quantization scheme is presented in the case of irreducible gauge theories. A realization…
Classical BRST charge and observables in reducible gauge theories
Andrei V. Bratchikov
We study the construction of the classical Becchi-Rouet-Stora-Tyutin (BRST) charge and observables for arbitrary reducible gauge theory. Using a special coordinate system in the ex…
General solution of classical master equation for reducible gauge theories
A. V. Bratchikov
We give the general solution to the classical master equation (S,S)=0 for reducible gauge theories. To this aim, we construct a new coordinate system in the extended configuration…
On the computation of star products
A. V. Bratchikov
The problem of finding a generic star product on R^n is reduced to the computation of a skew-symmetric biderivation.
