Commutative Wiener-Hopf factorization of a matrix
Douglas Samuel Jones · Proceedings of the Royal Society of London A Mathematical and Physical Sciences · 1984
Abstract A class of n x n-matrices is given for which commutative Wiener-Hopf factorization is possible and the explicit factors are obtained. It is also shown that there are no other matrices with factors which commute if the factors possess distinct eigenvalues.
