Innovation and factorization of the density of a regular PC sequence

  1. Andrzej Makagon


In this paper we study an innovation representation of a periodically correlated (PC) sequence and describe the factorization of the densities of a regular PC sequence generated by its innovation. As a byproduct we obtain a certain factorization of vector analytic functions which may be of interest in the theory of Hardy spaces.
