Dual formulation for higher spin gauge fields in (A)dSd

We obtain dual actions for spin s⩾2 massless fields in (A)dSd by solving different algebraic constraints in the same first-order theory. Flat space dual higher spin actions obtained by Boulanger, Cnockaert and Henneaux [JHEP 0306 (2003) 60, hep-th/0306023] by solving differential constraints are shown to result from our formulation in a sort of quasi-classical approximation for the flat limit. The case of s=2 is considered in detail.
