摘要: A system of perturbed equations motion with quadratic nonlinearity is considered. New estimates the Lyapunov function are established and two conclusions formulated. constraints presented. For coupled systems equations, boundedness conditions for some variables established. Practical in given domains initial subsequent perturbations quasi-linear considered as an example.
