Abstract

We investigate the soliton structure of novel (2+1)-dimensional nonlinear partial differential evolution(NLPDE) equations which may govern the behavior of a barothropic relaxing medium beneath high-frequency perturbations. As a result, we may derive some soliton solutions amongst which three typical pattern formations with loop-, cusp- and hump-like shapes., Comment: 4 pages

Abstract

In the present work, we investigate the soliton structure of the Vakhnenko equation with a 'dissipative' term, by means of the Hirota's method. As a result, we unearth three kinds of soliton solutions depending upon the dissipation parameter. We further find that the scattering behavior among such structures exhibits a peculiar feature that may be the fission phenomenon., Comment: 19 pages, 11 figures

Abstract

We derive a (1+1)-dimensional nonlinear evolution equation (NLE) which may model the propagation of high-frequency perturbations in a relaxing medium. As a result, this equation may possess three typical solutions depending on a dissipative parameter., Comment: 7 pages, 6 figures

Abstract

In this paper, we examined the behavior of the modulated wave patterns and nonlinear supratransmission phenomenon in gyrotropy molecular chains where the first-neighbor and third-neighbor interactions are considered. We have established the propagation modes through the dispersion law showing two cutoff frequencies. Through the numerical simulation, we have depicted modulated waves, solitons interaction as well as the modulation instability growth rates brought by the variation of the third-neighbor interaction and effective mass. As it was predicted that the group velocities vanish at the carrier waves, we have uncoupled a system of the coupled nonlinear Schrödinger equation by neglecting the elastic interaction to drive one end of the chains. The driven amplitude generates the train of waves in the system. For a specific time of propagation, we have shown how the variation of driven amplitude can induce instability in the forbidden gap. The obtained results have opened new features to the train of pulses in gyrotropy molecular chains.
