In this paper we obtain an explicit central intertwining lifting for row contractions. This is used to prove Kaftal-Larson-Weiss and Foias ¸-Frazho H . -H 2 suboptimization type results for the noncommutative (resp. commutative) analytic Toeplitz algebra F . n (resp. W . n ). The algebra F . n (resp

## Abstract We show that the pseudocontinuability of a matrix‐valued Schur function __θ__ in the unit disk is completely determined by the properties of the maximal shift and maximal coshift contained in a corresponding contractive operator __T__ which has the characteristic operator function __θ._
