Optical soliton perturbation and conservation law with Kudryashov’s refractive index having quadrupled power-law and dual form of generalized nonlocal nonlinearity

Abstract

The current paper obtains soliton solutions for Kudryashov’s law which stem from quadrupled-power law and dual form of nonlocal nonlinearity. A full spectrum of soliton solutions are derived. The conservation law is also exhibited to paint a complete picture to the model.
