Verblunsky Parameters and Linear Spectral Transformations [PDF]

Methods and Applications of Analysis, 2009
In this paper 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.
