چکیده
The (2+1)-dimensional Davey-Stewartson-like equations with variable coefficients have the applications in ultra-relativistic degenerate dense plasmas and Bose-Einstein condensates. Via Bell polynomials symbolic computation, bilinear form, Backlund transformation Lax pair for such are obtained. Based on Hirota method, we construct soliton solutions, analyze elastic collisions constant coefficients, observe that solitons no longer keep rectilinear propagation display different shapes because of coefficients. Besides, localized excitations derived through separation.

Bäcklund-Darboux Transformations and Melnikov Analysis for Davey-Stewartson II Equations
The Bäcklund-Darboux transformations are successfully utilized to construct heteroclinic orbits of Davey-Stewartson II equations through an elegant iteration of the transformations. In [17], we successfully built Melnikov vectors with the gradients of Floquet discriminants. Since there is no Floquet discriminant for Davey-Stewartson equations (in contrast to nonlinear Schrödinger equations [17]...
متن کاملQuadratic-Argument Approach to the Davey-Stewartson Equations
The Davey-Stewartson equations are used to describe the long time evolution of a threedimensional packets of surface waves. Assuming that the argument functions are quadratic in spacial variables, we find in this paper various exact solutions modulo the most known symmetry transformations for the Davey-Stewartson equations.
متن کاملSurfaces in the four-space and the Davey–Stewartson equations
The Weierstrass representation for surfaces in R3 [8, 13] was generalized for surfaces in R4 in [12] (see also [4]). This paper uses the quaternion language and the explicit formulas for such a representation were written by Konopelchenko in [9] for constructing surfaces which admit soliton deformation governed by the Davey–Stewartson equations. This generalizes his results from [8] where he in...

We study two coupled systems of nonlinear partial differential equations, namely, generalized Boussinesq-Burgers equations and 2 1 -dimensional Davey-Stewartson equations. The Lie symmetry method is utilized to obtain exact solutions of the generalized Boussinesq-Burgers equations. The travelling wave hypothesis approach is used to find exact solutions of the 2 1 dimensional Davey-Stewartson eq...
