Applying the Czédli-Schmidt Sequences to Congruence Properties of Planar Semimodular Lattices
Following Grätzer and Knapp, 2009, a planar semimodular lattice L is rectangular, if the left boundary chain has exactly one doubly-irreducible element, cl, and the right boundary chain has exactly one doubly-irreducible element, cr, and these elements are complementary.
