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…

Generalized inversion of the Hochschild coboundary operator and deformation quantization
A. V. Bratchikov
Using a derivative decomposition of the Hochschild differential complex we define a generalized inverse of the Hochschild coboundary operator. It can be applied for systematic comp…
