New realizations of observables in dynamical systems with second class constraints
A. V. Bratchikov
In the Dirac bracket approach to dynamical systems with second class constraints observables are represented by elements of a quotient Dirac bracket algebra. We describe families o…

First class functions in constrained second class systems
A. V. Bratchikov
Generators of the algebra of first class functions in a system with second class constraints are found. It is shown that first class functions form algebras with respect to the Dir…
