A nonlinear approach to generalized factorization of matrix functions
M. Cristina Câmara, A. F. dos Santos · Birkhäuser Basel eBooks · 1998
The generalized factorization of some classes of 2 ß 2 matrix symbols is determined by reduction to the study of certain scalar non-linear Riemann-Hilbert problems. This method is applied to several types of matrix functions, whose factorization is explicitly obtained.
