Localized coherent structures of the Davey-Stewartson equation in the bilinear formalism
نویسنده
چکیده
Recent studies on (2 + 1 )-dimensional integrable systems have shown the existence of solutions describing localized coherent structures with remarkable dynamical properties.‘*2 Unlike one-dimensional solitons these structures do not preserve, in general, their form upon interaction2 and may undergo processes of fusion and fission.3p4 The basic model exhibiting these solutions is the DaveyStewartson (DS) equation:

Explode-Decay Dromions in the Non-Isospectral Davey-Stewartson I (DSI) Equation
In this letter, we report the existence of a novel type of explode-decay dromions, which are exponentially localized coherent structures whose amplitude varies with time, through Hirota method for a nonisospectral Davey-Stewartson equation I discussed recently by Jiang. Using suitable transformations, we also point out such solutions also exist for the isospectral Davey-Stewartson I equation it...
متن کاملOn a Discrete Davey-stewartson System
We propose a differential difference equation in R × Z and study it by Hirota’s bilinear method. This equation has a singular continuum limit into a system which admits the reduction to the Davey-Stewartson equation. The solutions of this discrete DS system are characterized by Casorati and Grammian determinants. Based on the bilinear form of this discrete DS system, we construct the bilinear B...
متن کاملA class of coherent structures and interaction behavior in Multidimensions
We solve the (2+1)-dimensional Davey-Stewartson (DS) equation, a multidimensional analog of the nonlinear Schrödinger equation. A rather general solution for the variables separation with two arbitrary functions is first obtained by applying a special Bäcklund transformation and introducing the seed solutions. And then some new special types of two-dimensional coherent structures are obtained. ...
متن کاملThe Davey-Stewartson I Equation on the Quarter Plane with Homogeneous Dirichlet Boundary Conditions
Dromions are exponentially localised coherent structures supported by nonlinear integrable evolution equations in two spatial dimensions. In the study of initial-value problems on the plane, such solutions occur only if one imposes nontrivial boundary conditions at infinity, a situation of dubious physical significance. However it is established here that dromions appear naturally in the study ...
متن کاملRogue waves in the Davey-Stewartson I equation.
General rogue waves in the Davey-Stewartson-I equation are derived by the bilinear method. It is shown that the simplest (fundamental) rogue waves are line rogue waves which arise from the constant background with a line profile and then disappear into the constant background again. It is also shown that multirogue waves describe the interaction of several fundamental rogue waves. These multiro...
