Аннотация
We develop a perturbation theory for the evolution of solitary waves in quadratic nonconservative nonlinear media. The expressions derived for the solitons' amplitude and width permit us to estimate straightforwardly the damping-amplification rate of an arbitrary soliton of the unperturbed system. The analytical results obtained agree well with numerical experiments.
