Abstract The Kundu-Mukherjee-Naskar equation can be used to address certain optical soliton dynamics in the (2+1) dimensions. In this paper, we aim to find its periodic wave solution by the Hamiltonian-based algorithm. Compared with the existing results, they have a good agreement, which strongly proves the correctness of the proposed method. Finally, the numerical results are presented in the form of 3-D and 2-D plots. The results in this work are expected to shed a bright light on the study of the periodic wave solution in physics.

In this paper, we consider the generalized b-equation ut - uxxt + (b + 1)u2ux = buxuxx + uxxx. For a given constant wave speed, we investigate the coexistence of multifarious exact nonlinear wave solutions including smooth solitary wave solution, peakon wave solution, smooth periodic wave solution, single singular wave solution and periodic singular wave solution. Not only is the coexistence shown, but the concrete expressions are given via phase analysis and special integrals. From our work, it can be seen that the types of exact nonlinear wave solutions of the generalized b-equation are more than that of the b-equation. Many previous results are turned to our special cases. Also, some conjectures and questions are presented.

The set of coupled difference equations describing the dynamics of a monatomic chain is reduced to that of uncoupled anharmonic oscillators through the use of the translational invariance of the equations. Poincaré’s perturbation scheme is then used to obtain a space- and time-wise periodic wave solution together with a nonlinear dispersion relation between frequency, wavenumber and the amplitude. For all wavelengths, the frequency of vibration is observed to increase beyond the corresponding value for the linear case by terms proportional to the square of the amplitude multiplied by the coefficients of the cubic as well as quartic interactions. This solution of the lattice equations suggests a class of solutions of the generalized Korteweg-de Vries (K. de V.) equation which is related to the long wave limit of the nonlinear lattice by means of a semicharacteristic variable stretching transforma­tion. Numerical results for the dispersion relations are presented for the semi-empirical Morse, Born-Meyer and Lennard-Jones potentials. For these physical examples, the con­tributions of the cubic and quartic terms of the interaction potential are found to be of the same order.

We investigate the traveling wave solutions and their bifurcations for the BBM-likeB(m,n)equationsut+αux+β(um)x−γ(un)xxt=0by using bifurcation method and numerical simulation approach of dynamical systems. Firstly, for BBM-likeB(3,2)equation, we obtain some precise expressions of traveling wave solutions, which include periodic blow-up and periodic wave solution, peakon and periodic peakon wave solution, and solitary wave and blow-up solution. Furthermore, we reveal the relationships among these solutions theoretically. Secondly, for BBM-likeB(4,2)equation, we construct two periodic wave solutions and two blow-up solutions. In order to confirm the correctness of these solutions, we also check them by software Mathematica.

Analytic wave solutions including homoclinic wave, kink wave and soliton solutions for the 2D coupled complex Ginzburg–Landau equations are obtained using the auxiliary function method, Hirota method and the ansatz function technique under certain constraint conditions of coefficients in equations, respectively. The result shows that there exists a kink-wave solution which tends to one and the same periodic wave solution as time tends to infinite.
