Abstract: The aim of this note is to make explicit the connection between the Nehari problem and certain class of orthogonal polynomials on the unit circle obtained in a recursive way. A sequence of Schur-type parameters for this problem is also obtained.

Classification (MSC2000): 42A70, 42A05, 30E05.
