Using Lie-transform techniques, we derive higher-order corrections to the path-averaged model governing evolution of Ž . dispersion-managed solitons in the spectral domain. The result holds in the case of arbitrary including moderate and strong dispersion. The general theory is illustrated by deriving the exact formulas q for a specific symmetric dispersion map. q 2000 Published by Elsevier Sci...
