Pm. Lavrov et Py. Moshin, DYNAMICAL-SYSTEMS WITH IRREDUCIBLE CONSTRAINTS IN THE SP(2)-COVARIANTFORMALISM, Theoretical and mathematical physics, 102(1), 1995, pp. 60-68
For dynamical system with irreducible first-class constraints and in t
he framework of an expansion in powers of the fields of the ghost and
auxiliary sectors to third order inclusively, solutions of the equatio
ns for the generating functionals in the Sp(2)-covariant formalism of
generalized canonical quantization are found.
