    "abstract": "The perturbation theory based on the Riemann-Hilbert problem is developed for\nthe modified nonlinear Schr{\\\"o}dinger equation which describes the propagation\nof femtosecond optical pulses in nonlinear single-mode optical fibers. A\ndetailed analysis of the adiabatic approximation to perturbation-induced\nevolution of the soliton parameters is given. The linear perturbation and the\nRaman gain are considered as examples.",
