有限分配格的主同余的极小表示

Minimal representations of a finite distributive lattice by principal congruences of a lattice

G. Grätzer, H. Lakser

摘要:

设有限分配格$D$同构于有限格$L$的同余格.令$Q$表示$D$中对应于该同构下的主同余的那些元素。则$Q$包含$0,1 \in D$和$D$的所有连接不可约元.如果$Q$恰好包含这些元素,我们说$L$是$D$通过格$L$的主同余的极小表示。利用主同余的极小表示刻画了有限分配格$D$,并证明了$D$至多有两个对偶原子.

英文摘要:

Let the finite distributive lattice $D$ be isomorphic to the congruence lattice of a finite lattice $L$. Let $Q$ denote those elements of $D$ that correspond to principal congruences under this isomorphism. Then $Q$ contains $0,1 \in D$ and all the join-irreducible elements of $D$. If $Q$ contains exactly these elements, we say that $L$ is a minimal representations of $D$ by principal congruences of the lattice $L$. We characterize finite distributive lattices $D$ with a minimal representation by principal congruences with the property that $D$ has at most two dual atoms.
