Query: Towards the Fradkin-Vasiliev formalism in three dimensions   In this paper we show that using frame-like gauge invariant formulation for
the massive bosonic and fermionic fields in three dimensions the free
Lagrangians for these fields can be rewritten in the explicitly gauge invariant
form in terms of the appropriately chosen set of gauge invariant objects. This
in turn opens the possibility to apply the Fradkin-Vasiliev formalism to the
investigation of possible interactions of such fields.
