1. Gauge (in)dependence and background field formalism / Lavrov, Peter M.
It is shown that the gauge invariance and gauge dependence properties of effective action for Yang-Mills theories should be considered as two independent issues in the background field formalism. [...]

2. General conversion method for constrained systems / Batalin, Igor A. ; Lavrov, Peter M.
We reformulate in a systematic way the conversional approach in its most general and compact form. [...]

3. Multiplicative renormalization of Yang–Mills theories in the background-field formalism / Batalin, Igor A. ; Lavrov, Peter M. ; Tyutin, Igor V.
In the paper, within the background field method, the structure of renormalizations is studied as for Yang–Mills fields interacting with a multiplet of spinor fields. [...]

4. Superfield generating equation of field–antifield formalism as a hyper-gauge theory / Batalin, Igor A. ; Lavrov, Peter M.
Within a superfield approach, we formulate a simple quantum generating equation of the field–antifield formalism. [...]

5. Generalized sigma model with dynamical antisymplectic potential and non-Abelian de Rham's differential / Batalin, Igor A. ; Lavrov, Peter M.
For topological sigma models, we propose that their local Lagrangian density is allowed to depend non-linearly on the de Rham's “velocities” DZA . [...]

6. Closed description of arbitrariness in resolving quantum master equation / Batalin, Igor A. ; Lavrov, Peter M.
In the most general case of the Delta exact operator valued generators constructed of an arbitrary Fermion operator, we present a closed solution for the transformed master action in terms of the original master action in the closed form of the corresponding path integral. [...]

7. Legendre transformations and Clairaut-type equations / Lavrov, Peter M. ; Merzlikin, Boris S.
It is noted that the Legendre transformations in the standard formulation of quantum field theory have the form of functional Clairaut-type equations. [...]

10. Finite anticanonical transformations in field–antifield formalism / Batalin, Igor A. ; Lavrov, Peter M. ; Tyutin, Igor V.
We study the role of arbitrary (finite) anticanonical transformations in the field–antifield formalism and the gauge-fixing procedure based on the use of these transformations. [...]
