A remark on Lagrange structures for unfolded field theory
D.S. Kaparulin ; S.L. Lyakhovich ; A.A. Sharapov ;
Date 12 Dec 2010
AbstractAny system of local field equations, be it Lagrangian or not, can be equivalently formulated in so-called unfolded form. General unfolded equations are not Lagrangian even if the corresponding model was Lagrangian before unfolding. The Lagrange anchor, being a map from the space of field equations to the space of fields, can exist for non-Lagrangian equations. The Lagrange anchor, endows general (not necessarily Lagrangian) field equations, with several important properties possessed by Lagrangian systems. In particular, the Lagrange anchor makes possible to quantize the dynamics, and it also connects symmetries with conservation laws. In this paper, we study the structure of the Lagrange anchor compatible with the unfolded form of field equations, and establish its basic properties. We provide an explicit construction of the Lagrange anchor for the scalar field equations in the unfolded form. This construction is applicable to a broad class of field theories.
