摘要：

The authors consider the nonlinear systems ẋ = h(y) – F(x), ẏ = –g(x) in which g (x) may be not differentiable and the system can be nonsymmetric. Some conditions which ensure that there exists an infinite number of limit cycles are obtained. A problem about centerfocus put forward by R. Conti has been answered. © 1998, Appl. Math. J.
