Degenerate elliptic solutions of the quintic complex one-dimensional Ginzburg-Landau equation

A subset of traveling wave solutions of the quintic complex Ginzburg-Landau equation (QCGLE) is presented in compact form. The approach consists of the following parts. - Reduction of the QCGLE to a system of two ordinary differential equations (ODEs) by a traveling wave ansatz. - Solution of the system for two (ad hoc) cases relating phase and amplitude. - Presentation of the solution for both cases in compact form. - Presentation of constraints for bounded and for singular positive solutions by analyzing the analytical properties of the solution by means of a phase diagram approach. The results are exemplified numerically

2-Soliton-solution of the Novikov-Veselov equation

Based on a superposition method recently proposed to obtain 1-solitary wave solutions of the KdV-Burgers equation \cite{Yua2005}, we show that this method can also be used to find a 2-solitary wave solution of the Novikov-Veselov equation. Thus, it seems that the method of Yuanxi and Jiashi in general is not restricted to constructing 1-solitary wave solutions of nonlinear wave and evolution equations (NLWEEs).

Superposition in nonlinear wave and evolution equations

Real and bounded elliptic solutions suitable for applying the Khare-Sukhatme superposition procedure are presented and used to generate superposition solutions of the generalized modified Kadomtsev-Petviashvili equation (gmKPE) and the nonlinear cubic-quintic Schroedinger equation (NLCQSE).
