Abstract This paper secures cubic–quartic optical solitons of Kudryashov's equation with Hamiltonian perturbations that appear with maximum intensity. Bright, dark, singular and combo singular soliton solutions are recovered with F–expansion scheme. The conserved quantities are obtained by implementing multiplier approach.

三次四次光学孤子扰动和守恒定律与 Kudryashov 折射率定律

摘要 本文利用以最大强度出现的哈密顿扰动确保了 Kudryashov 方程的三次-四次光学孤子。亮、暗、奇异和组合奇异孤子解用 F 扩展方案恢复。守恒量是通过实施乘法器方法获得的。
