| Abstract: |
| In this paper, we consider non-matchable distributive lattices. By introducing the meet-irreducible cell with respect to a perfect matching of a plane elementary bipartite graph and giving its characterizations, we obtain a new class of non-matchable distributive lattices, and extend a result on non-matchable distributive lattices with a cut element. |
| Key words: plane (weakly) elementary bipartite graph Z-transformation directed graph meet-irreducible cell non-matchable distributive lattice planarity |
