可数格的主同余序集

The ordered set of principal congruences of a countable lattice

Gabor Czedli

摘要:

对于格L,设Princ L表示L的主同余的有序集.在一篇开创性的论文中,G. Gratzer的特点是有序集Princ L的有限格L;在这里,我们做同样的可数格。他还表明,每一个有界有序集H是同构的Princ L的有界格L。我们证明了一个相关的陈述:如果一个最小元序集H是一个主阶理想链的并,则H同构于某个格L的主L.

英文摘要:

For a lattice L, let Princ L denote the ordered set of principal congruences of L. In a pioneering paper, G. Gratzer characterized the ordered sets Princ L of finite lattices L; here we do the same for countable lattices. He also showed that each bounded ordered set H is isomorphic to Princ L of a bounded lattice L. We prove a related statement: if an ordered set H with least element is the union of a chain of principal order ideals, then H is isomorphic to Princ L of some lattice L.
