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

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

Non-central m-point formula in method of lines for solving the Korteweg-de Vries (KdV) equation
Journal of Umm Al-Qura University for Applied SciencesAbstract 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 ...

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

SymmetryThe main aim of this article is to modify the space-time fractionalKdV equations using the Bessel operator. The triple Laplace transform decomposition method (TLTDM) is proposed to find the solution for a time-fractional singular KdV coupled system of equations. Three problems are discussed to check the accuracy and illustrate the effectiveness of this
