Multi-type solitary wave solutions of Korteweg–de Vries (KdV) equation
International Journal of Modern Physics B, 2023In this paper, we explore how to generate solitary, peakon, periodic, cuspon and kink wave solution of the well-known partial differential equation Korteweg–de Vries (KdV) by using exp-function and modified exp-function methods. The presented methods construct more efficiently almost all types of soliton solution of KdV equation that can be rarely ...

Scattering theory for the Korteweg-De Vries (KdV) equation and its Hamiltonian interpretation
Physica D: Nonlinear Phenomena, 1986The paper deals with the Korteweg-de Vries equation of the form \(u_ t- 6uu_ x+u_{xxx}=0\) and shows that the scattering transform for it is not canonical in the naive sense as it produces ''paradoxes'', one of which is also presented. An explanation of this phenomenon is found, a correct Hamiltonian formulation of the scattering theory is proposed. It

International Journal of Geometric Methods in Modern Physics, 2021
In this work, we develop a novel method to obtain numerical solution of well-known Korteweg–de Vries (KdV) equation. In the novel method, we generate differentiation matrices for spatial derivatives of the KdV equation by using delta-shaped basis functions (DBFs). For temporal integration we use a high order geometric numerical integrator based on Lie

Abstract The non-linear Miura transformation, which converts the N -soliton solution of the modified KdV equation into an N -soliton solution for the KdV equation itself, is related to an unitary transformation of the operators associated with these equations.

The Korteweg-de Vries Equation (KdV-Equation)
1981This is the classic example of an equation which exhibits solitons. Methods which are applicable to a large class of equations which exhibit solitons will be derived from the study of this equation and its properties, and we therefore devote a rather large part of this book to this topic.

The Korteweg–de Vries (KdV) Equation
Abstract In this chapter we study the quintessential model for propagation of surface waves in a nonlinear medium: the Korteweg-de Vries (KdV) equation. Its wide applicability stems from the fact that the KdV is a prototypical (normal form) partial differential equation (PDE) that supports nonlinear waves.R. Carretero-González +2 more

It is difficult to obtain exact solutions of the nonlinear partial differential equations (PDEs) due to the complexity and nonlinearity, especially for non-integrable systems. In this case, some reasonable approximations of real physics are considered, by means of the standard truncated expansion approach to solve real nonlinear system is proposed.
