Description
Complex geometric optics (CGO) solutions to d-bar problems appear in many
applications, for instance in Electrical Impedance Tomography and in
the scattering theory of integrable PDEs in two dimensions. We discuss various numerical approaches to construct CGO solutions to d-bar systems. Of particular interest is the limit of large values of the spectral parameter where the solutions have an essential singularity.
This is work in collaboration with K. McLaughlin, J. Sjöstrand and N. Stoilov.
