Parametrization of all minimal square spectral factors

Augusto Ferrante, György Michaletzky, Michele Pavon

Research output: Contribution to journalArticlepeer-review


Two different parametrizations of minimal square spectral factors are given. These parametrizations extend recent results by Picci and Pinzoni since they characterize spectral factors without specification on the zero or pole structure.
