Matrix orthogonal polynomials on the unit circle

Journal of Mathematical Physics, 1981
The properties of matrix orthogonal polynomials on the unit circle are investigated beginning with their recurrence formulas. The techniques of scattering theory and Banach algebras are used in the investigation. A matrix generalization of a theorem of Baxter is proved.
