Chromatic Classification of Dismantlable Lattices
Subscribe/Renew Journal
A complete classification of the class of dismantlable lattices in terms of chromatic numbers is given. In fact, it is proved that a dismantlable lattice is at most 3-chromatic and the class of 2-Chromatic dismantlable lattices is characterized by using the structure theorem for dismantlable lattices.
Keywords
Lattice, Dismantlable Lattice, Adjunct Operation, Covering Graph, Chromatic Number.
