Faddeev eigenfunctions for two-dimensional Schrodinger operators via the
Moutard transformation    [PDF]

I. A. Taimanov, S. P. Tsarev

We demonstrate how the Moutard transformation of two-dimensional Schrodinger operators acts on the Faddeev eigenfunctions on the zero energy level and present some explicitly computed examples of such eigenfunctions for smooth fast decaying potentials of operators with non-trivial kernel and for deformed potentials which correspond to blowing up solutions of the Novikov-Veselov equation.
