Abstract
In this paper we go deep into the connection between duality and fields redefinition for general bilinear models involving the 1-form gauge field . A duality operator is fixed based on "gauge embedding" procedure. Dual models are shown to fit in equivalence classes of models with same fields redefinitions.
