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.53 pages, no figures, v2: typos corrected; explanations, two appendices and references added, v3: minor corrections, reference addedHigh Energy Physics - Theorytext
