Rezumat

Center-affine invariant conditions of the stability of unperturbed motion were determined for differential systems in the plane with polynomial nonlinearities in non-critical cases and for differential systems in the plane with polynomial nonlinearities up to the fourth degree inclusive in critical cases.

Cuvinte-cheie
Differential systems, stability of unperturbed motion, center-affine comitant and invariant,

Sibirsky graded algebras.
