On the isochronism of the center of a system of nonlinear oscillations

1989
The author studies a system of differential equations of the form \(x'=y\), \(y'=P(x,y)\), \(P(0,0)=0\), where \(P(x,y)\) is a fourth degree polynomial. \textit{I. S. Kukles} [Dokl. Akad. Nauk SSSR 57, No. 4, 166 (1944)] found the necessary and sufficient conditions in order for the equilibrium point (0,0) of the system to be of a center type.
