Nonanalytic solutions of the KdV equation

open access: yesAbstract and Applied Analysis, Volume 2004, Issue 6, Page 453-460, 2004., 2004
We construct nonanalytic solutions to the initial value problem for the KdV equation with analytic initial data in both the periodic and the nonperiodic cases.

Periodic and Solitary Traveling Wave Solutions for the Generalized Kadomtsev-Petviashvili Equation, II [PDF]

open access: yes, 1998
. As a continuation of our previous work, we improve here some results on convergence of periodic KP traveling waves to solitary ones as period goes to infinity.

Darboux transformation for classical acoustic spectral problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 49, Page 3123-3142, 2003., 2003
We study discrete isospectral symmetries for the classical acoustic spectral problem in spatial dimensions one and two by developing a Darboux (Moutard) transformation formalism for this problem. The procedure follows steps similar to those for the Schrödinger operator. However, there is no one‐to‐one correspondence between the two problems.

Motion of Inextensible Quaternionic Curves and Modified Korteweg-de Vries Equation

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
Many curve evolutions have been determined which are integrable in recent times. The motion of curves can be defined by certain integrable equations including the modified Korteweg-de Vries.

Higher‐order KdV‐type equations and their stability

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 4, Page 215-220, 2001., 2001
We have derived solitary wave solutions of generalized KdV‐type equations of fifth order in terms of certain hyperbolic functions and investigated their stability. It has been found that the introduction of more dispersive effects increases the stability range.

Asymptotic stability of a Korteweg–de Vries equation with a two-dimensional center manifold

open access: yesAdvances in Nonlinear Analysis, 2018
Local asymptotic stability analysis is conducted for an initial-boundary-value problem of a Korteweg–de Vries equation posed on a finite interval [0,2⁢π⁢7/3]{[0,2\pi\sqrt{7/3}]}.

An explicit solution of coupled viscous Burgers′ equation by the decomposition method

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 11, Page 675-680, 2001., 2001
We consider a coupled system of viscous Burgers′ equations with appropriate initial values using the decomposition method. In this method, the solution is calculated in the form of a convergent power series with easily computable components. The method does not need linearization, weak nonlinearity assumptions or perturbation theory.

p‐adic difference‐difference Lotka‐Volterra equation and ultra‐discrete limit

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 4, Page 251-260, 2001., 2001
We study the difference‐difference Lotka‐Volterra equations in p‐adic number space and its p‐adic valuation version. We point out that the structure of the space given by taking the ultra‐discrete limit is the same as that of the p‐adic valuation space. Since ultra‐discrete limit can be regarded as a classical limit of a quantum object, it implies that

Periodic and Solitary Wave Solutions for the One-Dimensional Cubic Nonlinear Schrödinger Model

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
Using a similar approach as Korteweg and de Vries, [19], we obtain periodic solutions expressed in terms of the Jacobi elliptic function cn, [3], for the self-focusing and defocusing one-dimensional cubic nonlinear Schrödinger equations.
