Rezumat

We find conditions for a singular point O(0,0) of a center or a focus type to be a center, in a cubic differential system with one invariant straight line. The presence of a center at O(0,0) is proved by using the method of rational reversibility

Se determină condițiile de existență a centrului pentru un sistem diferențial cubic cu punctul singular O(0,0) de tip centru sau focar ce posedă o dreaptă invariantă. Prezența centrului se demonstrează aplicând metoda reversibilității raționale

Cuvinte-cheie
Cubic differential system, center problem, invariant straight lines, rational reversibility,

sistem diferențial cubic, problema centrului, drepte invariante, reversibilitate rațională.
