For instance, solitons have been a subject of intense research during the past decades in the context of laser propagation in nonlinear optical media.
The study of the Ricci solitons in contact geometry has begun with the work of Ramesh Sharma ([22], [14]).
Optical solitons are seen by a cancellation of nonlinear.
As a result, solitons (coherent structures) or shock waves may be formed [16,17], ensembles of solitons may emerge [18,19], interaction of 2D solitons may lead to amplification [20], patterns of soliton trajectories demonstrate the character of motion in time [18,19], interaction with the embedded microstructure reveals the emergence of wave ensembles--solitary trains [21], seismic waves may undergo amplification [22,23], etc.
As it is known, the combined impact of negative dispersion and the nonlinear self-phase modulation leads to the formation of solitons in SMF [9,10], when the impact of dispersion and nonlinear self-phase modulation balance each other out.
We would like to demonstrate that the Hirota method can be used to explore various types of closed-form solutions: interaction solutions of lumps with solitons, kinks, line-solitons, resonance solutions, and one- or two-stripe solitons; and two classes of breather solutions (time periodic or space periodic solutions).
When it comes to real-world settings rather than the idealized context of the integrable NLSE, one has to deal with the impact of power loss on solitons. This issue was treated with perturbation methods by several authors [6-11].
The nonlinear coupled Schroodinger-Boussinesq equation (SBE) governs the propagation of optical solitons in a dispersive optical fiber and is a very important equation in the area of theoretical and mathematical physics.
The existing records indicate that internal waves in this basin may have the appearance of internal solitons with an amplitude of 5-15 m and length of 200-400 m (Nagovitsyn & Pelinovsky 1988; Nagovitsyn et al.
Solitons resulting of the propagation in HNLF2 experience a significant amount of SPM when propagating in HNLF1.
The results on validation of proposed method of solution are presented in Section 6 which includes study of motion of single solitary wave, interaction of two solitary waves, interaction of three solitary waves and evolution of solitons. We make a detailed comparison with available data in order to confirm and illustrate our theoretical analysis.
