Hierarchies of the Korteweg–de Vries Equation Related to Complex Expansion and Perturbation
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...
