Bilinearization of a Generalized Derivative Nonlinear Schrödinger Equation

چکیده
A generalized derivative nonlinear Schrödinger equation, iqt + qxx + 2iγ|q| qx + 2i(γ − 1)q q x + (γ − 1)(γ − 2)|q| q = 0, is studied by means of Hirota’s bilinear formalism. Soliton solutions are constructed as quotients of Wronski-type determinants. A relationship between the bilinear structure and gauge transformation is also discussed. ∗e-mail: [email protected] §

متن کاملBilinearization of Coupled Nonlinear Schrödinger Type Equations: Integrabilty and Solitons
Considering the coupled envelope equations in nonlinear couplers, the question of integrability is attempted. It is explicitly shown that Hirota’s bilinear method is one of the simple and alternative techniques to Painlevé analysis to obtain the integrability conditions of the coupled nonlinear Schrödinger (CNLS) type equations. We also show that the coupled Hirota equation introduced by Tasgal...
متن کاملNew integrable systems of derivative nonlinear Schrödinger equations with multiple components
(Received 25 June 1998, revised version received 05 January 1999) The Lax pair for a derivative nonlinear Schrödinger equation proposed by Chen-Lee-Liu is generalized into matrix form. This gives new types of integrable coupled derivative nonlinear Schrödinger equations. By virtue of a gauge transformation, a new multi-component extension of a derivative nonlinear Schrödinger equation proposed ...
متن کاملAffine Lie group approach to a derivative nonlinear Schrödinger equation and its similarity reduction
The generalized Drinfel’d-Sokolov hierarchies studied by de Groot-HollowoodMiramontes are extended from the viewpoint of Sato-Wilson dressing method. In the A (1) 1 case, we obtain the hierarchy that include the derivative nonlinear Schrödinger equation. We give two types of affine Weyl group symmetry of the hierarchy based on the Gauss decomposition of the A (1) 1 affine Lie group. The fourth ...
