In this note, we introduce the concepts of weak finitely regular relations and weak hypercontinuous posets. It is proved that when a binary relation $$\rho :X/\rightarrow Y$$ ρ : X / → Y satisfies a certain condition, $$\rho $$ ρ is weak finitely regular if and only if $$(\varphi _{\rho }(X,Y),\subseteq )$$ ( φ ρ ( X , Y ) , ⊆ ) is a weak hypercontinuous poset. For a poset P , we get that the relation $$\not \le $$ ≰ on P is weak finitely regular if and only if P is weak hypercontinuous.

弱有限正则关系及应用

在这篇笔记中,我们介绍了弱有限正则关系和弱超连续偏序集的概念。证明了当二元关系 $$\rho :X/\rightarrow Y$$ ρ : X / → Y 满足一定条件时,$$\rho $$ ρ 是弱有限正则当且仅当 $$(\ varphi _{\rho }(X,Y),\subseteq )$$ ( φ ρ ( X , Y ) , ⊆ ) 是一个弱超连续偏序集。对于偏序集 P ,我们得到 P 上的关系 $$\not \le $$ ≰ 是弱有限正则当且仅当 P 是弱超连续的。
