Traveling Wave Solutions of Space-Time Fractional Generalized Fifth-Order KdV Equation

open access: yesAdvances in Mathematical Physics, 2017
The Korteweg-de Vries (KdV) equation, especially the fractional higher order one, provides a relatively accurate description of motions of long waves in shallow water under gravity and wave propagation in one-dimensional nonlinear lattice.

Bäcklund Transformations for Nonlinear Differential Equations and Systems

open access: yesAxioms, 2019
In this work, new Bäcklund transformations (BTs) for generalized Liouville equations were obtained. Special cases of Liouville equations with exponential nonlinearity that have a multiplier that depends on the independent variables and first-order ...

Structure-Preserving Physics-Informed Neural Network for the Korteweg--de Vries (KdV) Equation

open access: yes
Physics-Informed Neural Networks (PINNs) offer a flexible framework for solving nonlinear partial differential equations (PDEs), yet conventional implementations often fail to preserve key physical invariants during long-term integration. This paper introduces a \emph{structure-preserving PINN} framework for the nonlinear Korteweg--de Vries (KdV ...

A combined sine-Gordon and modified Korteweg-de Vries hierarchy and its algebro-geometric solutions

open access: yes, 1997
We derive a zero-curvature formalism for a combined sine-Gordon (sG) and modified Korteweg-de Vries (mKdV) equation which yields a local sGmKdV hierarchy.

Non-central m-point formula in method of lines for solving the Korteweg-de Vries (KdV) equation

open access: yesJournal of Umm Al-Qura University for Applied Sciences
Abstract The present study is committed to devising efficient spatial discretization with two non-central difference formulae incorporated in the method of lines (MOL). The method is then implemented numerically on the renowned dispersive evolution equation, the Korteweg-de Vries (KdV) model while infusing Euler and fourth-order Rung-Kutta ...

Nonlinear Evolution Equations of the Soliton Type: Old and New Results

open access: yesProceedings
An overview on the study of nonlinear evolution equations of soliton type is provided. In addition, 5th-order nonlinear evolution equations are shown to be connected to the Caudrey–Dodd–Gibbon–Sawada–Kotera (CDGSK) equation via Bäcklund transformations ...
