Optical soliton perturbation, group invariants and conservation laws of perturbed Fokas–Lenells equation Academic Article uri icon


  • © 2018 Elsevier Ltd This paper obtains bright, dark and singular optical soliton solutions to the perturbed Fokas-Lenells equation by the aid of Lie symmetry analysis. The conserved laws are also retrieved and finally the conserved quantities are computed from these densities.
