| Rezumat | ||||||
For the autonomous bidimensional polynomial systems of differential equations with nonlinearities of the fourth degree the GL(2, R)-invariant recurrence equations for determination of the Lyapunov quantities were established. Moreover, the general form of Lyapunov quantities for the mentioned systems is obtained. For a class of such systems the necessary and sufficient GL(2,R)-invariant conditions for the existence of center are given. |
