Optical solitons are special waves that maintain their shape while traveling. Hence, solitary optical waves have great significance when it comes to representing pulse propagation through nonlinear partial differential equations. In our research, we

In this paper, we consider three models of non-linear Schrödinger’s equations (NLSEs) via It\^{o} sense. Specifically, we study these equations forced by multiplicative noise via the Brownian motion process. There are numerous approaches for conve

Nonlinear oscillators with geometric stiffness terms can be used to model a range of structural elements such as cables, beams and plates. In particular, single-degree-of-freedom (SDOF) systems are commonly studied in the literature by means of diffe

In this paper, we consider a generalized form of nonlinear Radhakrishnan-Kundu-Lakshmanan equation. The generalized exponential rational function method has been used to obtain some novel exact optical solutions. Several numerical simulations are pro

In this paper we studied the 2D Kundu–Mukherjee–Naskar model which governs many nonlinear processes from various fields of Physics, as for example the propagation of the nonlinear waves through optical fibres, rogue waves in hydrodynamics, or oth

The main goal of this paper is to propose an efficient technique in solving partial differential equations inspired by the improvement of a known method. To this end, we modified the generalized exponential rational function method to obtain analytic
