摘要
研究二阶自治Birkhoff系统的奇点、闭轨和极限环 ,以及与其相关的稳定性问题 .给出奇点判据和闭轨判据 .
The singular points, closed orbits, limit cycles and the stability of equilibria of second order autonomous Birkhoff systems are studied. The criteria for singular points and closed orbits are given, and they are applied to the bifurcation of equilibrium points for second order autonomous Birkhoff systems.
