C. Claude, SOLUTION OF 3 WAVES INTERACTION TYPE MODELS WITH NONTRIVIAL ASYMPTOTIC AND BOUNDARY-CONDITIONS, Journal of mathematical physics, 36(9), 1995, pp. 4841-4862
In the following we introduce a new way to solve the Cauchy problem fo
r nonvanishing potentials at infinity for the spectral problem of the
Zakharov and Shabat, Ablowitz, Kaup, Newell, and Segur (ZS-AKNS) hiera
rchy. Then we apply the results to solve a class of coupled systems, w
ith this nonvanishing condition on the potential and with quite genera
l boundary conditions on the other fields. Finally we present an appli
cation to a physical system governed by a three waves interaction type
model. (C) 1995 American Institute of Physics.
