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.
