Extended nonlinear Schrödinger equation with higher-order odd and even terms and its rogue wave solutions
We consider an extended nonlinear Schrodinger equation with higher-order odd (third order) and even (fourth ¨ order) terms with variable coefficients. The resulting equation has soliton solutions and approximate rogue wave solutions. We present these solutions up to second order. Moreover, specific constraints on the parameters of higher-order terms provide integrability of the resulting equation, providing a corresponding Lax pair. Particular cases of this equation are the Hirota and the...[Show more]
