    Abstract

    This paper is devoted to the study of general (Laurent) polynomial
    modifications of moment functionals on the unit circle, i.e., associated with
    hermitian Toeplitz matrices. We present a new approach which allows us to study
    polynomial modifications of arbitrary degree.
