Communicated by C.R. Doering
Abstract:An
extended tanh-function method is proposed for constructing multiple travelling
wave solutions of nonlinear partial differential equations (PDEs) in a unified
way. The key idea of this method is to take full advantages of a Riccati equation
involving a parameter and use its solutions to replace the tanh function in
the tanh-function method. It is quite interesting that the sign of the parameter
can be used to exactly judge the numbers and types of these travelling wave
solutions. In addition, by introducing appropriate transformations, it is
shown that the extended tanh-function method still is applicable to nonlinear
PDEs whose balancing numbers may be any nonzero real numbers. Some illustrative
equations are investigated by this means and new travelling wave solutions
are found.

Abstract. An explicit N -fold Darboux transformation with multiparameters for a kind of coupled derivative nonlinear Schr¨ odinger equation is constructed with the help of a gauge transformation of a spectral problem. As a reduction, a Darboux transformation of the Gerdjikov–Ivanov equation is obtained. Furthermore, the explicit soliton-like solutions of the Gerdjikov–Ivanov equation are given by applying its Darboux transformation.

Abstract:A spectral problem and the associated hierarchy of Schr¨ odinger type equations are proposed. It is shown that the hierarchy is integrable in Liouville’s sense and possesses multi-Hamiltonian structure. It is found that several kinds of important equation such as the Kaup–Newell (KN) equation, the Chen–Lee–Liu (CLL) equation, the Gerdjikov–Ivanov (GI) equation, the modified Korteweg–de Vries equation and the Sharma–Tasso–Olever equation are members in the hierarchy as its special reductions. Moreover, KN, CLL and GI equations are described by using a unified generalized derivative Schr¨ odinger equation involving a parameter, and their Hamiltonian structure and Lax pairs are also given by unified and explicit formulae.
