Factorization Theory for Singular Integral Operators with Flip
The invertibility of singular integral operators with flip on the
unit circle is equivalent to the invertibility of
Toeplitz-plus-Hankel operators with a matrix symbol of a particular
structure. We show how to develop a factorization theory for such
Toeplitz-plus-Hankel operators. The kind of factorization differs
from the usual generalized Wiener-Hopf factorization, but is
related to it. Some examples where the factorization can be
constructed explicitly will be also discussed.
