Nonlocal-derivative NLS equations and group-invariant soliton solutions
Abstract A coupled Chen–Lee–Liu (CLL) system is proposed and its linear Lax pair is given. Many kinds of nonlocal-derivative NLS (DNLS) equations arise from the group symmetry reductions of the coupled CLL system. P ˆ T ˆ C ˆ $\hat{P}\hat{T}\hat{C}$ -symmetry invariant one-soliton solution and perio...
