摘要
For each non-singular real algebraic curve f = 0 of degree m we exhibit an explicit vector field of degree m which has precisely the bounded components of f = 0 as limit cycles. The degree of the system is optimal for a generic class of algebraic curves and improves the significantly the bounds given by Winkel.
