%0 Journal Article %T Classes de Wadge potentielles et th¨Ļor¨¨mes d'uniformisation partielle %A Dominique Lecomte %J Mathematics %D 2007 %I arXiv %X We want to give a construction as simple as possible of a Borel subset of a product of two Polish spaces. This introduces the notion of potential Wadge class. Among other things, we study the non-potentially closed sets, by proving Hurewicz-like results. This leads to partial uniformization theorems, on big sets, in the sense of cardinality or Baire category. %U http://arxiv.org/abs/0710.0133v1
