NON-CANONICAL OPERATORS AND GAUGE FIXING PROCEDURE
Pages 24-33

Abstract
An approach of the extended BRST Lagrangean formalism via its equivalence with the Hamiltonian one is
proposed. This approach will allow a better understanding of the ghost spectrum and of the form of the
master equations. We will also point out the key role played by the non-canonical operators which appear in
the Lagrangean context for the gauge fixing procedure. To be more concrete, the case of an irreducible first
rank theory endowed with a sp (3) BRST symmetry will be considered.
