关于弱紧拓扑半格$\exp_nλ$
On feebly compact semitopological semilattice $\exp_nλ$
摘要:
研究了半格$\left(\exp_nλ,\cap\right)$上的弱紧移位连续拓扑。证明了这样的$T_1$ -拓扑是序列紧的当且仅当它是$\mathfrak{D}(ω)$ -紧的.
英文摘要:
We study feebly compact shift-continous topologies on the semilattice $\left(\exp_nλ,\cap\right)$. It is proved that such $T_1$-topology is sequentially pracompact if and only if it is $\mathfrak{D}(ω)$-compact.
