Abstract
Motivated by the theory of nonstationary linear systems a number of problems in the theory of analytic functions have analogues in the setting of upper-triangular operators, where the complex variable is replaced by a diagonal operator. In this paper we focus on the analogue of interpolation in the Hardy space H2 and study a two-sided Nudelman type interpolation problem in the framework of upper-triangular Hilbert-Schmidt operators.
