Lattice tolerances and congruences

Gábor Czédli, George Grätzer

We prove that a tolerance relation of a lattice is a homomorphic image of a congruence relation.

Congruence structure of planar semimodular lattices: The General Swing Lemma

Gábor Czédli, George Grätzer, Harry Lakser

The Swing Lemma of the second author describes how a congruence spreads from a prime interval to another in a slim (having no sublattice), planar, semimodular lattice. We gen…
