چکیده
|
The kaup-newell system describes the pulse propagation in optical fibers. this paper applies the semi-inverse method to construct the system’s variational formulations, two trial-variational formulations with an unknown function are established, and a detailed derivation is given to determine the unknown function. finally, the kaup-newell system with two variables is converted to a partial differential equation with only one variable.
