Novel lump solutions of the modified Kadomtsev-Petviashvili-I equation
Tianwei Qiu, Zhen Wang
We construct novel higher-order lump solutions of the modified Kadomtsev-Petviashvili-I (mKP-I) equation by applying the generalized long-wave limit method with spectral perturbati…

Numerical inverse scattering transform for the derivative nonlinear Schrodinger equation
Shikun Cui, Zhen Wang
In this paper, we develop the numerical inverse scattering transform (NIST) for solving the derivative nonlinear Schrodinger (DNLS) equation. The key technique involves formulating…
