Blowing-up solutions of the time-fractional dispersive equations

open access: yesAdvances in Nonlinear Analysis, 2021
This paper is devoted to the study of initial-boundary value problems for time-fractional analogues of Korteweg-de Vries, Benjamin-Bona-Mahony, Burgers, Rosenau, Camassa-Holm, Degasperis-Procesi, Ostrovsky and time-fractional modified Korteweg-de Vries ...

Symmetries and reductions of integrable nonlocal partial differential equations

open access: yes, 2019
In this paper, symmetry analysis is extended to study nonlocal differential equations, in particular two integrable nonlocal equations, the nonlocal nonlinear Schr\"odinger equation and the nonlocal modified Korteweg--de Vries equation.

Symmetries for the Semi-Discrete Lattice Potential Korteweg–de Vries Equation

open access: yesMathematics
In this paper, we prove that the isospectral flows associated with both the x-part and the n-part of the Lax pair of the semi-discrete lattice potential Korteweg–de Vries equation are symmetries of the equation.

Theoretical investigation of the behavior of spherical ion- acoustic solitons in two-temperature plasma [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2019
The propagation of the small amplitude ion-acoustic solitary waves (IASWs) is studied in a plasma containing cold fluid ions and multi-temperature electrons (cool and hot electrons) with the nonextensive distribution.

The Sylvester equation and integrable equations: I. The Korteweg-de Vries system and sine-Gordon equation [PDF]

open access: yes, 2014
The paper is to reveal the direct links between the well known Sylvester equation in matrix theory and some integrable systems. Using the Sylvester equation $\boldsymbol{K} \boldsymbol{M}+\boldsymbol{M} \boldsymbol{K}=\boldsymbol{r}\, \boldsymbol{s}^{T}$

A Paley-Wiener Theorem for Periodic Scattering with Applications to the Korteweg-de Vries Equation [PDF]

open access: yes, 2010
Consider a one-dimensional Schroedinger operator which is a short range perturbation of a finite-gap operator. We give necessary and sufficient conditions on the left, right reflection coefficient such that the difference of the potentials has finite ...

The Generalized Harry Dym Equation

open access: yes, 2003
The Harry Dym equation is generalized to the system of equations in the manner as the Korteweg - de Vries equation is generalized to the Hirota - Satsuma equation . The Lax and Hamiltonian formulation for this generalization is given.This generalized Lax

On integrability of one third-order nonlinear evolution equation

open access: yes, 2003
We study one third-order nonlinear evolution equation, recently introduced by Chou and Qu in a problem of plane curve motions, and find its transformation to the modified Korteweg - de Vries equation, its zero-curvature representation with an essential ...

Solitary Wave Solutions of the Generalized Rosenau-KdV-RLW Equation

open access: yesMathematics, 2020
This paper investigates the solitary wave solutions of the generalized Rosenau–Korteweg-de Vries-regularized-long wave equation. This model is obtained by coupling the Rosenau–Korteweg-de Vries and Rosenau-regularized-long wave equations. The solution of
