• TITLE: Fractional Optical Solitons and Fractional Noether’s Theorem with Ortigueira’s Centered Derivatives

  AUTHORS: Jorge Fujioka, Manuel Velasco, Argel Ramírez

  ABSTRACT: This paper shows that the centered fractional derivatives introduced by Manuel Duarte Ortigueira in 2006 are useful in the description of optical solitons. It is shown that we can construct a fractional extension of the nonlinear Schrödinger (NLS) equation which incorporates Ortigueira’s derivatives and has soliton solutions. It is also shown that this fractional NLS equation has a Lagrangian density and can be derived from a variational principle. Finally, a fractional extension of Noether’s theorem is formulated to determine the conserved quantities associated to the invariances of the action integral under infinitesimal transformations.
