Interpolation Khrushchev-type formulas for structured operators, inequalities and asymptotic relations

Alexander Sakhnovich

We show that interpolation results in the -nodes theory may be considered as Khrushchev-type formulas. If separation of the well-known Verblunsky (Schur) coefficients occurs in…

-nodes, factorisation of spectral matrix functions and corresponding inequalities

Alexander Sakhnovich

Using factorisation and Arov-Krein inequality results, we derive important inequalities (in terms of -nodes) in interpolation problems.
