Second Class Constraints in a Higher-Order Lagrangian Formalism
I. A. Batalin, K. Bering, P. H. Damgaard
Abstract
We consider the description of second-class constraints in a Lagrangian path integral associated with a higher-order Δ-operator. Based on two conjugate higher-order Δ-operators, we also propose a Lagrangian path integral with Sp(2) symmetry, and describe the corresponding system in the presence of second-class constraints.
