本文证明了2-圆盘D2的C_1保定向嵌入f的周期轨道O与不动点P相连,即对应的周期轨道{Φt(O)}t_≥_0和{Φ_t(P)}t_≥_0在S3中以纽结的形式相连。
Abstract We prove that any periodic orbit O of a C1 orientation-preserving embedding f of the 2-disc D2 is linked with a fixed point P in the sense that the corresponding periodic orbits {Φt(O)}t ≥ 0 and {Φt(P)}t ≥ 0 of any torus flow Φt suspending f are linked as knots in S3.
