This paper studies polarized cubic–quartic solitons that are modeled by Fokas–Lenells equation in birefringent fibers. Two integration schemes recovered a spectrum of soliton solutions to the model. Subsequently, the bright solitons compute the corresponding conserved quantities from the respective densities that are recovered by the multiplier approach.

受扰动 Fokas-Lenells 模型的三次-四次偏振光孤子和守恒定律

本文研究了双折射光纤中由 Fokas-Lenells 方程建模的偏振立方四次孤子。两种积分方案恢复了模型的一系列孤子解。随后，亮孤子根据乘法器方法恢复的相应密度计算相应的守恒量。
