ON THE EQUIVALENCE BETWEEN THE UNIFIED AND STANDARD VERSIONS OF CONSTRAINT DYNAMICS
Igor Anatol'evich Batalin, Igor Viktorovich Tyutin · Modern Physics Letters A · 1993
The structure of physical operators and states of the unified constraint dynamics is studied. The genuine second class constraints encoded are shown to be the superselection operators. The unified constrained dynamics is established to be physically-equivalent to the standard BFV-formalism with constraints split.
