关于局部不动点或周期点性质

On local fixed or periodic point properties

Alejandro Illanes, Pawł Krupski

摘要:

空间X具有局部不动点性质LFPP(局部周期点性质LPPP),如果它具有开基$\mathcal{B}$,使得对于每个$B\in \mathcal{B}$,闭包$\overline{B}$具有不动点性质。弱版本wLFPP,wLPPP也被认为是度量连续区分所有这些属性的例子被构造。我们证明了对于平面或一维局部连通度量连续统的性质是等价的。

英文摘要:

A space X has the local fixed point property LFPP, (local periodic point property LPPP) if it has an open basis $\mathcal{B}$ such that, for each $B\in \mathcal{B}$, the closure $\overline{B}$ has the fixed (periodic) point property. Weaker versions wLFPP, wLPPP are also considered and examples of metric continua that distinguish all these properties are constructed. We show that for planar or one-dimensional locally connected metric continua the properties are equivalent.
