Dilations and rigid factorisations on noncommutative Lp-spaces

Research output: Contribution to journalArticlepeer-review


We study some factorisation and dilation properties of completely positive maps on noncommutative Lp-spaces. We show that Akcoglu's dilation theorem for positive contractions on classical (= commutative) Lp-spaces has no reasonable analog in the noncommutative setting. Our study relies on nonsymmetric analogs of Pisier's operator space valued noncommutative Lp-spaces that we investigate in the first part of the paper.
