Sublattices and standard congruences

  • G. Grätzer
  • E. T. Schmidt


In an earlier paper, the authors and H. Lakser proved that, for every lattice K and nontrivial congruence \( \phi \) of K, there is an extension L of K such that \( \phi \) is the restriction to K of a standard congruence on L. ¶In this note, we give a very short proof of this result in a stronger form the lattice L we construct is sectionally complemented and it has only one nontrivial congruence, the standard congruence.

Key words and phrases: Congruence lattice, congruence-preserving embedding, sectionally comple mented, standard.
