| Abstract: | We describe an approach to studying the center problem and local bifurcations of critical periods at infinity for a class of differential systems. We then solve the problem and investigate the bifurcations for a class of rational differential systems with a cubic polynomial as its numerator. |
| Keywords: | weak center isochronicity bifurcation of critical periods |
