Generating a New Higher-Dimensional Ultra-Short Pulse System: Lie-Algebra Valued Connection and Hidden Structural Symmetries

Abstract

We carry out the hidden structural symmetries embedded within a system comprising ultra-short pulses which propagate in optical nonlinear media. Based upon the Wahlquist-Estabrook approach, we construct the Liealgebra valued connections associated to the previous symmetries while deriving their corresponding Lax-pairs, which are particularly useful in soliton theory. In the wake of previous results, we extend the above prolongation scheme to higher-dimensional systems from which a new (2+ 1)-dimensional ultra-short pulse equation is unveiled along with its inverse scattering formulation, the application of which are straightforward in nonlinear optics where an additional propagating dimension deserves some attention.

Polarized waveguide excitations in microwave ferrites: The singularity structure analysis

“…With the different expressions of these arbitrary functions, some quite rich of higher-dimensional excitations would be generated while enriching the properties of the higher-dimensional ferrites [68]. In this perspective, we would follow other powerful methods of searching for the extension of the lower-dimensional systems to higher-dimensional ones as developed in the literature (see [69][70][71][72] and references therein).…”

Dynamical features and sensitivity visualization of thin-film Polarisation equation

“…Since their solutions are more expressive in describing the dynamics of waves in the material of interest, the topic of these equations' integrability is raised once they are available. Numerous mathematical methods, such as the prolongation structure [7] and Painlevé analysis [8], are proposed as solutions to these concerns. The Hirota bilinear method, Kudryashov's method, the first integral approach, the sub-equation technique, the simple hyperbolic function ansatzes, the hyperbolic tangent methods, etc are some examples of mathematical tools that are more direct in providing analytical expressions of the solution to nonlinear equations [9][10][11][12][13][14][15][16].…”
