Inverse scattering transform for a new non-isospectral integrable non-linear AKNS model
Constructing integrable systems and solving non-linear partial differential equations are important and interesting in non-linear science. In this paper, Ablowitz-Kaup-Newell-Segur (AKNS)’s linear isospectral problem and its accompanied time evolution equation are first generalized by embed...

description |
Constructing integrable systems and solving non-linear partial differential
equations are important and interesting in non-linear science. In this
paper, Ablowitz-Kaup-Newell-Segur (AKNS)’s linear isospectral problem and
its accompanied time evolution equation are first generalized by embedding a
new non-isospectral parameter whose varying with time obeys an arbitrary
smooth enough function of the spectral parameter. Based on the generalized
AKNS linear problem and its evolution equation, a new non-isospectral Lax
integrable non-linear AKNS model is then derived. Furthermore, exact
solutions of the derived AKNS model is obtained by extending the inverse
scattering transformation method with new time-varying spectral parameter.
In the case of reflectinless potentials, explicit n-soliton solutions are
finally formulated through the obtained exact solutions. |
