论文摘要

如果每个紧凑型子集(c_k(x)$的每个紧凑型子集(resp。Contrent序列)是公平的,则称为({\ em sectientally}){\ em ascoli} {\ em ascoli} {\ em ascoli}是公平的,其中$ c_k(x)$表示所有实现持续的持续功能与x $ comptact the All x $ comptact-comptact oft the the the the topcmop,经典的Ascoli定理指出,每个紧凑的空间都是ascoli。我们表明,伪混合空间$ x $是asoli iff,它是依次是ascoli iff,它是有选择的$ω$结合的。

A Tychonoff space $X$ is called ({\em sequentially}) {\em Ascoli} if every compact subset (resp. convergent sequence) of $C_k(X)$ is equicontinuous, where $C_k(X)$ denotes the space of all real-valued continuous functions on $X$ endowed with the compact-open topology. The classical Ascoli theorem states that each compact space is Ascoli. We show that a pseudocompact space $X$ is Asoli iff it is sequentially Ascoli iff it is selectively $ω$-bounded.
