Abstract We show that the property of having only non-weak cut points is a Whitney property, and that having only shore points is not a Whitney property. We also note that the property of having only non-cut (non-weak cut, shore) points is not a Whitney reversible property. This complements a result due to E. Matsuhashi.

惠特尼水平的非弱切割、岸边和非切割点

摘要 我们证明只有非弱割点的性质是惠特尼性质，只有岸点不是惠特尼性质。我们还注意到，只有非切割（非弱切割，岸）点的性质不是惠特尼可逆性质。这补充了 E. Matsuhashi 的结果。
