Algebraic Curve Solution for Second-Order Polynomial Autonomous Systems Zhaosheng Feng In this paper, by the method of the analysis of algebraic curves and the division theorem for two complex variables, the nonexistence of the algebraic curve solution of the second-order polynomial autonomous systems in the complex plane is obtained. The results are of important significance in the qualitative theory of polynomial autonomous systems and the integrability of nonlinear ordinary differential equations.
