Finite lattices with isoform congruences
George Grätzer, Tamás Schmidt · 2003
Abstract. We call a lattice L isoform, if for any congruence relation Θof L, all congruence classes of Θare isomorphic sublattices. We prove that for every finite distributive lattice D, there exists a finite isoform lattice L such that the congruence lattice of L is isomorphic to D. 1.
