Invertibility characterization of scalar Wiener-Hopf plus Hankel
operators with essentially bounded Fourier symbols
The invertibility of Wiener-Hopf plus Hankel operators with
essentially bounded Fourier symbols is characterized via certain
factorization properties of the Fourier symbols. In addition, a
Fredholm criterion for these operators is also obtained and the
dimensions of the kernel and cokernel are described. The talk is
based on a joint paper with L. P. Castro.
