On the optimal focusing of solitons and breathers in long‐wave models [PDF]

open access: yesStudies in Applied Mathematics, 2019
AbstractConditions of optimal (synchronized) collisions of any number of solitons and breathers are studied within the framework of the Gardner equation (GE) with positive cubic nonlinearity, which in the limits of small and large amplitudes tends to other long‐wave models, the classic and the modified Korteweg–de Vries equations.

Akhmediev breathers and Peregrine solitary waves in a quadratic medium [PDF]

open access: yesOptics Letters, 2017
We investigate the formation of optical localized nonlinear structures, evolving upon a non-zero background plane wave, in a dispersive quadratic medium. We show the existence of quadratic Akhmediev breathers and Peregrine solitary waves, in the regime of cascading second-harmonic generation.

Some Exact Solutions to Generalized Kadomtsev-Petviashvili Equation

open access: yesAdvances in Mathematical Physics, 2022
Most of the papers have explored the interactions between solitons with a zero background, while reports about exact solutions for nonzero background are rare.

Two-breather solutions for the class I infinitely extended nonlinear Schrodinger equation and their special cases [PDF]

open access: yes, 2020
We derive the two-breather solution of the class I infinitely extended nonlinear Schrödinger equation. We present a general form of this multi-parameter solution that includes infinitely many free parameters of the equation and free parameters of the two

Breather Solutions of N-wave Equations

open access: yes, 2012
We consider $N$-wave type equations related to symplectic and orthogonal algebras. We obtain their soliton solutions in the case when two different $\mathbb{Z}_2$ reductions (or equivalently one $\mathbb{Z}_{2} \times \mathbb{Z}_{2}$-reduction) are imposed.

The rogue wave and breather solution of the Gerdjikov-Ivanov equation [PDF]

open access: yesJournal of Mathematical Physics, 2012
The Gerdjikov-Ivanov (GI) system of q and r is defined by a quadratic polynomial spectral problem with 2 × 2 matrix coefficients. Each element of the matrix of n-fold Darboux transformation (DT) for this system is expressed by a ratio of (n + 1) × (n + 1) determinant and n × n determinant of eigenfunctions, which implies the determinant representation ...

New dynamical behaviors for a new extension of the Shallow water model

open access: yesResults in Physics, 2022
The aim of this work, is to construct some novel solutions for a new extension of the shallow water model in (3+1)-dimensions. Based on two methods namely; simplified Hirota’s method and a long-wave method a class of solutions are reported.

Breathers and rogue waves for semilinear curl-curl wave equations

open access: yesJournal of Elliptic and Parabolic Equations, 2023
AbstractWe consider localized solutions of variants of the semilinear curl-curl wave equation $$s(x) \partial _t^2 U +\nabla \times \nabla \times U + q(x) U \pm V(x) \vert U \vert ^{p-1} U = 0$$ s ( x )
