Ward's solitions

, 1997
Using the `Riemann Problem with zeros' method, Ward has constructed exact solutions to a (2+1)-dimensional integrable Chiral Model, which exhibit solitons with nontrivial scattering.

Dissipative perturbations for the K(n,n) Rosenau-Hyman equation

, 2012
Compactons are compactly supported solitary waves for nondissipative evolution equations with nonlinear dispersion. In applications, these model equations are accompanied by dissipative terms which can be treated as small perturbations.

Self-adjointness of a generalized Camassa-Holm equation

, 2011
It is well known that the Camassa-Holm equation possesses numerous remarkable properties characteristic for KdV type equations. In this paper we show that it shares one more property with the KdV equation. Namely, Ibragimov has shown that the KdV and the

Local well-posedness for the two-component Benjamin-Ono equation

Advances in Nonlinear Analysis
The Cauchy problem for the two-component Benjamin-Ono equation is considered. It is shown that this problem is local well-posed in Hs(R)×Hs(R){H}^{s}\left({\mathbb{R}})\times {H}^{s}\left({\mathbb{R}}) for any s>9⁄8s\gt 9/8.

The Additional Symmetries for the BTL and CTL Hierarchies

, 2011
The Toda lattice (TL) hierarchy was first introduced by K.Ueno and K.Takasaki in \cite{uenotaksasai} to generalize the Toda lattice equations\cite{toda}. Along the work of E. Date, M. Jimbo, M. Kashiwara and T.

Almost sharp nonlinear scattering in one-dimensional Born-Infeld equations arising in nonlinear Electrodynamics

, 2017
We study decay of small solutions of the Born-Infeld equation in 1+1 dimensions, a quasilinear scalar field equation modeling nonlinear electromagnetism, as well as branes in String theory and minimal surfaces in Minkowski space-times.
