G-等度连续条件下若干点集的研究

The Research of Some Point Set Under the Condition of G-equicontinuity

  • 摘要: 在映射fG-等度连续的条件下,研究了G-链回归点、G-非游荡点、G-极限点和G-回归点之间的关系,得到如下结论:(1)RG(f)=WG(f)=ΩG(f); (2)WG(f)=CRG(f)=\bigcap\limits_n=1^\infty f^n(X); (3)fG-等度连续的当且仅当WG(f)中的所有点都是G-等度连续点。以上结论充实了度量G-空间中G-链回归点、G-非游荡点、G-极限点和G-回归点的理论。

     

    Abstract: The relationship among G-chain recurrent point, G-nonwandering point, G-limit point and G-recurrent point were studied under the condition that the map f is G-equicontinuous. The following conclusions are obtained: (1)RG(f)=WG(f)=ΩG(f); (2)WG(f)=CRG(f)=\bigcap\limits_n=1^\infty f^n(X); (3)f is G-equicontinuous if and only if all point in WG(f) are G-equicontinuous points. The above conclusions enrich the theory of G-chain recurrent point, G-nonwandering point, G-limit point, and G-recurrent point in metric G-space.
