Chains of KP, semi‐infinite 1‐Toda lattice hierarchy and Kontsevich integral

open access: yesJournal of Applied Mathematics, Volume 1, Issue 4, Page 175-193, 2001., 2001
There are well‐known constructions of integrable systems that are chains of infinitely many copies of the equations of the KP hierarchy “glued” together with some additional variables, for example, the modified KP hierarchy. Another interpretation of the latter, in terms of infinite matrices, is called the 1‐Toda lattice hierarchy.

B\"acklund-Darboux Transformations and Discretizations of Super KdV Equation [PDF]

open access: yes, 2014
For a generalized super KdV equation, three Darboux transformations and the corresponding B\"acklund transformations are constructed. The compatibility of these Darboux transformations leads to three discrete systems and their Lax representations.

Three‐dimensional Korteweg‐de Vries equation and traveling wave solutions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 6, Page 379-384, 2000., 2000
The three‐dimensional power Korteweg‐de Vries equation [ut+unux+uxxx] x+uyy+uzz=0, is considered. Solitary wave solutions for any positive integer n and cnoidal wave solutions for n = 1 and n = 2 are obtained. The cnoidal wave solutions are shown to be represented as infinite sums of solitons by using Fourier series expansions and Poisson′s summation ...

Nonclassical Approximate Symmetries of Evolution Equations with a Small Parameter [PDF]

open access: yes, 2006
We introduce a method of approximate nonclassical Lie-B\"acklund symmetries for partial differential equations with a small parameter and discuss applications of this method to finding of approximate solutions both integrable and nonintegrable equations ...

Existence of periodic traveling wave solutions to the generalized forced Boussinesq equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 22, Issue 3, Page 643-648, 1999., 1999
The generalized forced Boussinesq equation, utt − uxx + [f(u)]xx + uxxxx = h0, and its periodic traveling wave solutions are considered. Using the transform z = x − ωt, the equation is converted to a nonlinear ordinary differential equation with periodic boundary conditions.

On the support of solutions to the Zakharov-Kuznetsov equation [PDF]

open access: yes, 2010
In this article we prove that sufficiently smooth solutions of the Zakharov-Kuznetsov equation that have compact support for two different times are identically zero.Comment: Version of Dec 17/2010 contains simpler proof of Theorem 1.3 and new ...

Addendum to a paper of Craig and Goodman

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 17, Issue 4, Page 825-827, 1994., 1994
In [1], Craig and Goodman develop the geometrical optics solution of the linearized Korteweg‐deVries equation away from caustic, or turning, points. Here we develop an analogous solution valid at caustic points.

On a negative flow of the AKNS hierarchy and its relation to a two-component Camassa-Holm equation [PDF]

open access: yes, 2006
Different gauge copies of the Ablowitz-Kaup-Newell-Segur (AKNS) model labeled by an angle $\theta$ are constructed and then reduced to the two-component Camassa--Holm model.
