文摘We study solutions of the nonlinear Schroedinger equation (NLSE) and higher-order nonlinear Sehroedinger equation (HONLSE) with variable coefficients. By considering all the higher-order effect of HONLSE as a new dependent variable, the NLSE and HONLSE can be changed into one equation. Using the generalized Lie group reduction method (CLGRM), the abundant solutions of NLSE and HONLSE are obtained.
