Let G be a Borel class, or a Wadge class of Borel sets, and 2=d=? be a cardinal. A Borel subset B of R d is potentially in G if there is a finer Polish topology on R such that B is in G when R d is equipped with the new product topology. The author provides a way to recognize the sets potentially in G and applies this to the classes of graphs (oriented or not), quasi-orders and partial orders.
