The weak tightness wt ( X ) of a space X was introduced in Carlson (Topol Appl 249:103–111, 2018 ) with the property $$wt(X)\le t(X)$$ w t ( X ) ≤ t ( X ) . We investigate several well-known results concerning t ( X ) and consider whether they extend to the weak tightness setting. First we give an example of a non-sequential compactum X such that $$wt(X)=\aleph _0

论弱密到弱密

Carlson (Topol Appl 249:103–111, 2018 ) 中引入了空间 X 的弱紧密性 wt ( X ),其性质为 $$wt(X)\le t(X)$$ wt ( X ) ≤ t ( X ) 。我们研究了几个关于 t ( X ) 的众所周知的结果,并考虑它们是否扩展到弱密封性设置。首先我们给出一个非连续紧致 X 的例子,使得 $$wt(X)=\aleph _0
