The Batalin–Vilkovisky field–antifield action for systems with first-class constraints

The Batalin–Vilkovisky field–antifield action for systems with first-class constraints is given explicitly in terms of the canonical Hamiltonian, the hamiltonian constraints and the first-order hamiltonian gauge structure functions. It is shown that this action does not depend on the hamiltonian gauge structure functions of higher orders. A method for finding the lagrangian gauge structure tensors of all orders is presented. It is proven that the lagrangian gauge structure tensors do not depend on the hamiltonian gauge structure functions of second or higher orders.
