%0 Journal Article %T A non commutative sewing lemma %A Denis Feyel %A Arnaud De La Pradelle %A Gabriel Mokobodzki %J Mathematics %D 2007 %I arXiv %X In a preceding paper [E.J.ofProb.34,860-892,(2006)], we proved a sewing lemma which was a key result for the study of Holder continuous functions. In this paper we give a non-commutative version of this lemma with some applications. %U http://arxiv.org/abs/0706.0202v1
