The vector form of Kundu-Eckhaus equation and its simplest solutions
In our work a hierarchy of integrable vector nonlinear differential equations
depending on the functional parameter is constructed using a monodromy
matrix. The first equation of this hierarchy for
is vector analogue of the Kundu-Eckhaus
equation. When , the equations of this hierarchy turn into equations
of the Manakov system hierarchy. New elliptic solutions to vector analogue of
the Kundu-Eckhaus and Manakov system are presented. In conclusion, it is shown
that there exist linear transformations of solutions to vector integrable
nonlinear equations into other solutions to the same equations.Comment: 20 pages, 3 figure
