A remark on a polynomial matrix factorization theorem

Lasha Ephremidze, Ilya M. Spitkovsky

Research output: Contribution to journalArticlepeer-review


The Wiener-Hopf factorization of trigonometric polynomial matrix functions is considered and it is proved that the factors are matrices of trigonometric polynomials as well. The natural bounds for partial indices and for orders of the factors are obtained.
