约化环序与下半格

The reduced ring order and lower semi-lattices

W. D. Burgess, R. Raphael

摘要:

每个约化环$R$都有一个由$a\le b$定义的自然偏序,如果$a^2=ab$ ;它推广了布尔环上的自然序。本文研究了当$R$是一个下半格在这个顺序的例子从弱Baer环(PP-环)和环的连续函数。局部连通空间和基本不连通空间给出了环$C(X)$,它是这样的下半格。研究了满环同态上可数正交集的提升。

英文摘要:

Every reduced ring $R$ has a natural partial order defined by $a\le b$ if $a^2=ab$; it generalizes the natural order on a boolean ring. The article examines when $R$ is a lower semi-lattice in this order with examples drawn from weakly Baer rings (pp-rings) and rings of continuous functions. Locally connected spaces and basically disconnected spaces give rings $C(X)$ which are such lower semi-lattices. Liftings of countable orthogonal (in this order) sets over surjective ring homomorphisms are studied.
