有限格同余的一个公开问题

An open problem on congruences of finite lattices

George Grätzer

摘要:

设$L$是平面半模格.如果没有$\mthree$子格,我们称之为$L$ \emph{slim}。让我们定义一个\emph{SPS lattice}为一个细长的,平面的,半模格$L$。在2016年,我证明了SPS格的同余的一个性质(双覆盖性质),并提出了刻画它们的问题。从那时起,已经发表了50多篇论文,对这个问题做出了贡献。在本调查中,我提供了一个概述这一领域的主要贡献加博尔Czédli。

英文摘要:

Let $L$ be a planar semimodular lattice. We call $L$ \emph{slim}, if it has no $\mthree$ sublattice. Let us define an \emph{SPS lattice} as a slim, planar, semimodular lattice $L$. In 2016, I proved a property of congruences of SPS lattices (Two-cover Property) and raised the problem of characterizing them. Since then, more than 50 papers have been published contributing to this problem. In this survey, I provide an overview of this field with major contributions by Gábor Czédli.
