Disjoint Unions of Incidence Structures and Complete Lattices
František Machala, Vladimír Slezák · Czech digital mathematics library · 1999
Conceptual lattices of disjoint unions of incidence structures are studied in this paper.It is showed that these lattices are disjoint unions of their complete sublattices.An isomorphism between the ordered set of all disjoint unions of an incidence structure and the ordered set of all equivalence classes of disjoint unions of corresponding conceptual lattice is described.
