Abstract
We introduce a new subring (L) of (L) for a completely regular frame L and characterize pseudocompact frames via these subrings. Also we obtain several sufficient conditions on L which guarantee that the cozero part of generates L. Further, we prove that the Stone-Čech compactification βL of L is determined by these subrings whenever L is pseudocompact or strongly zero-dimensional. Finally, we have conjectured that if L is zero-dimensional and realcompact then the zero-dimensional (universal) compactification ζL of L is determined via these subrings.

关于ℛ(L)的某些子环的注释
摘要
我们引入一个新的子环(大号的)(大号)用于完全正帧大号和经由主环表征pseudocompact帧。此外,我们获得几个苏FFI cient条件大号其保证的cozero部分产生大号。此外,我们证明,只要L是伪紧实的或强零维的,L的Stone-Čech压缩βL就由这些子环确定。最后,我们推测,如果L为零维且紧实,则L的零维(通用)压缩ζL 通过这些子环确定。
