Verblunsky parameters and linear spectral transformations. (English) Zbl 1176.42021

Summary: We analyze the behavior of Verblunsky parameters for Hermitian linear functionals deduced from canonical linear spectral transformations of a quasi-definite Hermitian linear functional. Some illustrative examples are studied.
