Abstract

The relation graph of a finite lattice \(L\) is defined to be a simple graph with the elements of \(L\) as vertices and two distinct vertices are adjacent if and only if they are comparable in \(L\). We investigate the properties of relation graphs and characterize those lattices whose relation graphs are complete. The association between the relation graphs of isomorphic lattices is studied.

Keywords:

Lattice, simple graph, triangle free graph, isomorphism of lattices
