Analytical solutions of cylindrical and spherical dust ion-acoustic solitary waves

Results in Physics, 2019
In the present work, employing the conventional reductive perturbation method to the field equations of an unmagnetized dusty plasma consisting of inertial ions, Boltzmann electrons and stationary dust particles in the nonplanar geometry we derived ...

The 2D Kawahara equation on half-strip [PDF]

arXiv, 2014
We formulate on a half-strip an initial boundary value problem for the two-dmensional Kawahara equation. Existence and uniqueness of a regular solution as well as the exponential decay rate for the elevated norm of small solutions are proven.

KAM for autonomous quasi-linear perturbations of KdV [PDF]

arXiv, 2014
We prove the existence and stability of Cantor families of quasi-periodic, small amplitude solutions of quasi-linear (i.e. strongly nonlinear) autonomous Hamiltonian perturbations of KdV.

An initial-boundary value problem in a strip for two-dimensional Zakharov-Kuznetsov-Burgers equation [PDF]

arXiv, 2014
An initial-boundary value in a strip with homogeneous Dirichlet boundary conditions for two-dimensional Zakharov-Kuznetsov-Burgers equation is considered. Results on global well-posedness and long-time decay of solutions in Sobolev spaces are established.

Renormalized asymptotic solutions of the Burgers equation and the Korteweg-de Vries equation [PDF]

arXiv, 2015
The Cauchy problem for the Burgers equation and the Korteweg-de Vries equation is considered. Uniform renormalized asymptotic solutions are constructed in cases of a large initial gradient and a perturbed initial weak discontinuity.
