On the optimal solutions in spectral commutant lifting theory

Abstract

AbstractIn this note we give a property of the optimal solutions to the spectral commutant lifting theorem of H. Bercovici, C. Foias, and A. Tannenbaum (Trans. Amer. Math. Soc., in press) which shows that such solutions are spectral analogues of inner functions which appear as optimal solutions in classical dilation theory
