再论具有主同余的有限分配格的表示定理

Revisiting the representation theorem of finite distributive lattices with principal congruences

G. Grätzer, H. Lakser

摘要:

R.\,P.Dilworth指出,每个有限分配格$D$都可以表示为有限格$L$的同余格。一个更尖锐的形式发表在G。Grätzer和E.\,T. Schmidt在1962年提出了一个新的定理,要求$L$中的所有同余都是主同余。另一种变体,由作者和E. T. Schmidt构造了一个平面半模格$L$ .在本文中,我们合并了这两个结果:我们构造$L$作为一个平面半模格,其中所有的同余是主的。本文依赖于作者和E. T.施密特在1998年的论文中说。

英文摘要:

A classical result of R.\,P. Dilworth states that every finite distributive lattice $D$ can be represented as the congruence lattice of a finite lattice~$L$. A~sharper form was published in G.~Grätzer and E.\,T. Schmidt in 1962, adding the requirement that all congruences in $L$ be principal. Another variant, published in 1998 by the authors and E.\,T. Schmidt, constructs a planar semimodular lattice $L$. In this paper, we merge these two results: we construct $L$ as a planar semimodular lattice in which all congruences are principal. This paper relies on the techniques developed by the authors and E.\,T. Schmidt in the 1998 paper.
