On a Hardy space approach to the analysis of spectral factors

The paper presents a study of several problems related to spectral factorizations. We assume only a very weak form of coercivity for the spectral function and look at the set of all rectangular spectral factors Wm of given size m. The main object is the arithmetization of the geometry of these sets of minimal, stable spectral factors of given size by employing Hardy space techniques and the arithmetic of inner functions. Particular attention is paid to the study of various partial orders associated with the sets of spectral factors.
