Kinky periodic pulse and interaction of bell wave with kink pulse wave propagation in nerve fibers and wall motion in liquid crystals

open access: yesPartial Differential Equations in Applied Mathematics, 2020
In this article, we apply a direct influential approach namely enhanced modified simple equation (EMSE) method to integrate the Burgers–Huxley (BH) and FitzHugh–Nagumo (FHN) equations which explain nerve pulse propagation in nerve fibers, circuit theory ...

The local strong and weak solutions to a generalized Novikov equation

open access: yes, 2013
A nonlinear partial differential equation, which includes the Novikov equation as a special case, is investigated. The well-posedness of local strong solutions for the equation in the Sobolev space Hs(R) with s>32 is established.

Ward's solitions

open access: yes, 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.

On new types of integrable 4-wave interactions

open access: yes, 2012
We start with a Riemann-Hilbert Problems (RHP) with canonical normalization whose sewing functions depends on two or more additional variables. Using Zakharov-Shabat theorem we are able to construct a family of ordinary differential operators for which ...

RECURSION OPERATORS FOR RATIONAL BUNDLE ON sl(3,C) WITH Z2 × Z2 × Z2 REDUCTION OF MIKHAILOV TYPE

open access: yes, 2015
We consider the recursion operator related to a system introduced recently that could be considered as a generalization to a pole gauge generalized Zakharov-Shabat system on sl(3,C) but involving rational dependence on the spectral parameter and subject ...

The Additional Symmetries for the BTL and CTL Hierarchies

open access: yes, 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.

SOLITARY WAVE SOLUTIONS FOR A CLASS OF DISPERSIVE EQUATIONS

open access: yes, 2015
The focus of the present work is the one-dimensional nonlinear equation ut − uxxt + ux + uxxx + αuux = λ(uuxxx + 2uxuxx), (1) modeling the wave breaking phenomenon in the shallow water regime.

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

open access: yes, 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.

On the classification of scalar evolutionary integrable equations in $2+1$ dimensions

open access: yes, 2010
We consider evolutionary equations of the form $u_t=F(u, w)$ where $w=D_x^{-1}D_yu$ is the nonlocality, and the right hand side $F$ is polynomial in the derivatives of $u$ and $w$.
