Purely chromatic and hyper chromatic lattices
Madhukar M. Pawar, Amit S. Wadile · Asian-European Journal of Mathematics · 2019
We introduce the concepts of a hyper chromatic, a critically chromatic and a purely chromatic lattice. We obtain some characterizations for purely chromatic and hyper chromatic dismantlable lattices. We prove relationships between the chromatic number of two lattices and their linear sum, vertical sum and adjunct.
