The construction is closed to that of Smith but different. We use a more conceptual approach to simplify the proofs that P^\\vee is the cofree P-coalgebra functor and also the comonad generating P-coalgebras.\n  In a second part, when P is a linear or dg-operad over a field, we generalize the notion of representative functions of Block & Leroux and prove that P^\\vee(C) is simply the subobject of representative elements in the \"completed P-algebra\" P^\\wedge(C).
