Classical Nevanlinna-Pick Interpolation with Real Interpolation Points,xistence and uniqueness of the solutions are considered. In the case of nonuniqueness a description of all solutions is given which generalizes Potapov’s formula. Our results are obtained in two ways: in Sections 1–5 through the theory of selfadjoint extensions of a symmetric relation in a Hilbert s

On Classes of Realizable Operator-valued ,-functions,transformations of the transfer operator-valued functions (characteristic functions) of linear stationary conservative dynamic systems (Brodskii-Livsic rigged operator colligations). We specialize three subclasses of the class of all realizable operator-valued .-functions [.]. We give complete proof

Kolmogorov Decompositions and the Realization of Time Dependent Systems, of Hermitian kernels as a main tool for the solution of this problem. The uniqueness property of the minimal realization is characterized. Applications are given to the realization of time independent systems, including the connection with the Azizov realization theorem and with de Branges-Rovnyak

We point out the relationship between these results and those of Yu. Shmul’yan on mappings on the unit ball of operators by fractional linear transformations and extend
