摘要

。我们恢复了属于N. A. Kudryashov折射率的六次方幂律非线性型的自相位调制效应的亮、暗、奇异光孤子解的情况。已经实施了三种不同的集成方案。这是一个统一的里卡蒂方程，我们的新映射方案和我们对常见的N. a . Kudryashov方法的补充。列出了所有的孤子，并提到了它们存在的标准。最后，我们提取了三个合适的守恒定律。

Optical solitons and conservation laws associated with Kudryashov�s sextic power-law nonlinearity of refractive index

. We recover the cases of solutions in the shape of bright, dark and singular optical solitons for the self-phase modulation effect, which belongs to the type of N. A. Kudryashov’s sextic power-law nonlinearity of refractive index. Three different integration schemes have been implemented. These are a unified Riccati equation, our new mapping scheme and our addendum to the common N. A. Kudryashov’s method. All of the solitons are enlisted and the criterions of their existence are mentioned. Finally, we extract three appropriate conservation laws.
