A Hyperbolic Approximation of the Nonlinear Schrödinger Equation

open access: yesStudies in Applied Mathematics
ABSTRACT We study a first‐order hyperbolic approximation of the nonlinear Schrödinger (NLS) equation. We show that the system is strictly hyperbolic and possesses a modified Hamiltonian structure, along with at least three conserved quantities that approximate those of NLS.

Asymptotic Behavior of Solutions to the Damped Nonlinear Hyperbolic Equation [PDF]

open access: yesJournal of Applied Mathematics, 2013
We consider the Cauchy problem for the damped nonlinear hyperbolic equation inn-dimensional space. Under small condition on the initial value, the global existence and asymptotic behavior of the solution in the corresponding Sobolev spaces are obtained by the contraction mapping principle.

Approximate analytical solutions of nonlinear hyperbolic partial differential equation [PDF]

open access: yes, 2022
The Multistep Modified Reduced Differential Transform Method (MMRDTM) is proposed and implemented in this study to obtain solutions of hyperbolic partial differential equations. We examine at the nonlinear Schrodinger equation (NLSE).

Weak Solutions for a Simple Hyperbolic System [PDF]

open access: yes, 2001
The model studied concerns a simple first-order hyperbolic system. The solutions in which one is most interested have discontinuities which persist for all time, and therefore need to be interpreted as weak solutions.

Generalized Hyperbolic Function Solution to a Class of Nonlinear Schrödinger-Type Equations

open access: yesJournal of Applied Mathematics, 2012
With the help of the generalized hyperbolic function, the subsidiary ordinary differential equation method is improved and proposed to construct exact traveling wave solutions of the nonlinear partial differential equations in a unified way.

On nonlinear evolution equation of second order in Banach spaces

open access: yesOpen Mathematics, 2018
Here we study the existence of a solution and also the behavior of the existing solution of the abstract nonlinear differential equation of second order that, in particular, is the nonlinear hyperbolic equation with nonlinear main parts, and in the ...
