Actions, charges and off-shell fields in the unfolded dynamics approach

摘要

Within unfolded dynamics approach, we represent actions and conserved charges as elements of cohomology of the L. algebra underlying the unfolded formulation of a given dynamical system. The unfolded off-shell constraints for symmetric fields of all spins in Minkowski space are shown to have the form of zero curvature and covariant constancy conditions for 1-forms and 0-forms taking values in an appropriate star product algebra. Unfolded formulation of Yang-Mills and Einstein equations is presented in a closed form.
