Periodic Solutions of Nonlinear Equations Obtained by Linear Superposition [PDF]

open access: yes, 2002
We show that a type of linear superposition principle works for several nonlinear differential equations. Using this approach, we find periodic solutions of the Kadomtsev-Petviashvili (KP) equation, the nonlinear Schrodinger (NLS) equation, the $\lambda \

Rogue waves on the double-periodic background in the focusing nonlinear Schrödinger equation. [PDF]

open access: yesPhysical Review E, 2019
The double-periodic solutions of the focusing nonlinear Schrödinger equation have been previously obtained by the method of separation of variables. We construct these solutions by using an algebraic method with two eigenvalues.

Nonlinear Schrodinger equation and frequency saturation [PDF]

open access: yesAnalysis & PDE, 2011
We propose an approach that permits to avoid instability phenomena for the nonlinear Schrodinger equations. We show that by approximating the solution in a suitable way, relying on a frequency cut-off, global well-posedness is obtained in any Sobolev space with nonnegative regularity.

Singular standing-ring solutions of nonlinear partial differential equations

open access: yes, 2009
We present a general framework for constructing singular solutions of nonlinear evolution equations that become singular on a d-dimensional sphere, where d>1. The asymptotic profile and blowup rate of these solutions are the same as those of solutions of
