Web12 de abr. de 2024 · We consider the possibility of constructing a hierarchy of the complex extension of the Korteweg–de Vries equation (cKdV), which under the assumption that the function is real passes into the KdV hierarchy. A hierarchy is understood here as a family of nonlinear partial differential equations with a Lax pair with a common scattering operator. WebSpecifically, in Section 2, we review the connections between the Korteweg-deVries (KdV) and the modified Korteweg-deVries (mKdV) equations based on Miura’s transformation [Miu], and commutation methods. Appendix A summarizes the necessary commutation formulas needed in Section 2. In Section 3 we study soliton-like solutions of the mKdV ... 30新台币等于多少人民币
