Noether identities of a generic differential operator. The Koszul-Tate complex
G. Sardanashvily
Given a generic Lagrangian system, its Euler-Lagrange operator obeys Noether identities which need not be independent, but satisfy first-stage Noether identities, and so on. This c…
The variational bicomplex on graded manifolds and its cohomology
G. Sardanashvily
Lagrangian formalism on graded manifolds is phrased in terms of the Grassmann-graded variational bicomplex, generalizing the familiar variational bicomplex for even Lagrangian syst…
On the BV quantization of gauge gravitation theory
D. Bashkirov, G. Sardanashvily
Quantization of gravitation theory as gauge theory of general covariant transformations in the framework of Batalin-Vilkoviski (BV) formalism is considered. Its gauge-fixed Lagrang…
Space-time BRST symmetries
D. Bashkirov, G. Sardanashvily
Bearing in mind BV quantization of gauge gravitation theory, we extend general covariant transformations to the BRST ones.
On algebras of gauge transformations in a general setting
G. Sardanashvily
We consider a Lagrangian system on a fiber bundle and its gauge transformations depending on derivatives of dynamic variables and gauge parameters of arbitrary order. We say that g…
Polysymplectic Hamiltonian formalism and some quantum outcomes
G. Giachetta, L. Mangiarotti, G. Sardanashvily
Covariant (polysymplectic) Hamiltonian field theory is formulated as a particular Lagrangian theory on a polysymplectic phase space that enables one to quantize it in the framework…
