Analytical Soliton Solutions of the Coupled Radhakrishnan‐Kundu‐Lakshmanan Equation via Three Techniques

Abstract

The analytical soliton solutions to the coupled Radhakrishnan-Kundu-Lakshmanan (RKL) model are greatly important for birefringent fibers without the effect of four-wave mixing (4WM). A significant number of general and standard analytical soliton solutions to this model have been extracted using three powerful techniques, namely the generalized Kudryashov’s method, the extended tanh method, and the G ′ / G -expansion method in this article. The schematic profiles of the solitons are sketched using the symbolic mathematical program Mathematica and are presented in two and three dimensions. The reported solutions might be helpful in explaining the RKL equation’s physical significance as well as some other related nonlinear phenomena that appear in engineering and nonlinear sciences.

Assessment of Hydrogen Mobility utilising MCDM method

“…Mg at 300 °c with 18 bar h 2 ≈80% efficiency within 15 min for Nano particles absorbed. For different MgH 2 amounts [6]. A challenge in introducing hydrogen current price vehicles and infrastructure is infrastructure partners and automakers both 'phases iii' significantly higher in committed to providing 'vehicles', because large quantities cost significantly reducing and Germany hydrogen as the world's leading marketplace for mobility paving the way for change.…”

Optical soliton solutions of the stochastic perturbed Radhakrishnan-Kundu-Lakshmanan equation via Itô Calculus

“…The solutions of the Radhakrishnan-Kundu-Lakshmanan equation have been studied extensively by numerous authors [12][13][14][15][16][17][18][19][20][21]. New solutions for the RKL equation, including multiple-optical solitons and singular periodic wave solutions, have been presented using efficient computational methods and providing physical interpretations through 3D and 2D plots [22].…”
