The factorization problem: Some known results and open questions

Albrecht Böttcher, Ilya M. Spitkovsky

Research output: Contribution to journalArticlepeer-review


This is a concise survey of some results and open problems concerning Wiener-Hopf factorization and almost periodic factorization of matrix functions. Several classes of discontinuous matrix functions are considered. Also sketched is the abstract framework which unifies the two types of factorization.
