Dressing approach to the nonvanishing boundary value problem for the
AKNS hierarchy    [PDF]

J. F. Gomes, Guilherme S. Franca, A. H. Zimerman

We propose an approach to the nonvanishing boundary value problem for
integrable hierarchies based on the dressing method. Then we apply the method
to the AKNS hierarchy. The solutions are found by introducing appropriate
vertex operators that takes into account the boundary conditions.
