Abstract

In this paper we construct an unfolded formulation for the massive bosonic higher spins in three dimensions as well as for their partially massless limit of the maximal depth. We begin with the equations for the one-forms coming from the frame-like gauge invariant Lagrangians for such fields and then we supplement them with the infinite number of equations for the appropriately chosen set of zero-forms.
