Solitary waves due to x(2):x(2) cascading [PDF]

open access: yes, 1994
Solitary waves in materials with a cascaded x(2):x(2) nonlinearity are investigated, and the implications of the robustness hypothesis for these solitary waves are discussed. Both temporal and spatial solitary waves are studied.

Solvability of Nonlinear Wave Equation with Nonlinear Integral Neumann Conditions

open access: yesInternational Journal of Analysis and Applications, 2023
In this paper, we examine a nonlinear hyperbolic equation with a nonlinear integral condition. In particular, we prove the existence and the uniqueness of the linear problem by the Fadeo Galerkin method, and by applying an iterative process to some ...

On scattering for NLS: from Euclidean to hyperbolic space [PDF]

open access: yes, 2008
We prove asymptotic completeness in the energy space for the nonlinear Schrodinger equation posed on hyperbolic space in the radial case, in space dimension at least 4, and for any energy-subcritical, defocusing, power nonlinearity. The proof is based on

Abundant Explicit and Exact Solutions for the Variable Coefficient mKdV Equations

open access: yesAbstract and Applied Analysis, 2013
This paper is concerned with the variable coefficients mKdV (VC-mKdV) equation. First, through some transformation we convert VC-mKdV equation into the constant coefficient mKdV equation.
