Gauge Independence of the Lagrangian Path Integral in a Higher-Order Formalism
I. A. Batalin, K. Bering, P. H. Damgaard
Abstract
We propose a Lagrangian path integral based on gauge symmetries generated by a symmetric higher-order Δ-operator, and demonstrate that this path integral is independent of the chosen gauge-fixing function. No explicit change of variables in the functional integral is required to show this.
