By using the direct method of Hirota, explicit multi-soliton solutions are found for the generalized nonlinear Schr?dinger equation with higherorder corrections which describes the ultra-short pulse propagation along monomode optical fibers.

When Lax pairs have property of anti-Hermitian evolution, the 2×2 matrix form Riemann problem with zeros is solved explicitly. And the multi-soliton solutions of the NLS equation and the sG equation are also found explicitly.
