Let 1<p≠2<∞ and let Spn be the associated Schatten von Neumann class over n×n matrices. We prove new characterizations of unital positive Schur multipliers Spn→Spn which can be dilated into an invertible complete isometry acting on a non-commutative Lp-space. Then we investigate the infinite dimensional case.
