Measures on the unit circle and unitary truncations of unitary operators
Maria J. Cantero, Leandro Moral, Luis Velazquez
In this paper we obtain new results about the orthogonality measure of orthogonal polynomials on the unit circle, through the study of unitary truncations of the corresponding unit…

Minimal representations of unitary operators and orthogonal polynomials on the unit circle
M. J. Cantero, L. Moral, L. Velazquez
In this paper we prove that the simplest band representations of unitary operators on a Hilbert space are five-diagonal. Orthogonal polynomials on the unit circle play an essential…
