In this paper we study the phase portraits in the Poincaré disk of the reversible vector fields of type (2;0) having generic bifurcations around a symmetric singular point p. We also prove the nonexistence of any periodic orbit surrounding p. We point out that some numerical computations were necessary in order to control the number of limit cycles.

具有对称奇异性的(2; 0)可逆矢量场的相图

在本文中,我们研究了在(2; 0)类型的可逆矢量场的Poincaré圆盘中的相像,这些矢量场在对称奇异点p周围具有一般的分叉。我们还证明了围绕p的任何周期性轨道都不存在。我们指出,为了控制极限循环数,必须进行一些数值计算。
