This article uses the dressing method to investigate nonlocal nonlinear evolution equations starting from the matrix partial derivative problem. A hierarchy of equations associated with 2 x 2 matrix problem is derived, including the nonlocal extended modified Korteweg-de Vries (emKdV) equation. N-soliton solutions of the nonlocal emKdV equation are constructed based on the matrix partial derivative problem by selecting a suitable spectral transformation matrix.
Starting from the matrix partial derivative problem, the dressing method is employed to investigate the nonlocal nonlinear evolution equations. A hierarchy of nonlocal nonlinear evolution equations associated with 2 x 2 matrix problem, which contains the nonlocal extended modified Korteweg-de Vries (emKdV) equation, is derived via using recursive operator for the first time. Finally, via selecting a proper spectral transformation matrix, the N-soliton solutions of the nonlocal emKdV equation are constructed based on the matrix partial derivative problem.
