Abstract:

A planar semimodular lattice $L$ is slim if $\mathsf M_3$ is not a sublattice of $L$. In a recent paper, G. Czédli introduced a very powerful diagram type for slim, planar, semimodular lattices, the $\mathcal{C}_1$-diagrams. This short note proves the existence of such diagrams.

Keywords:

$\mathcal{C}_1$-diagrams, slim planar semimodular lattice
