Congruence Lattices of Uniform Lattices


I.Athal, M.Karthivel
Abstract

In this chapter we prove that every finite distributive lattice D can be represented as the congruence lattice of finite uniform lattice L. Infact we prove that “For any finite distributive lattice D, there exists a finite uniform lattice L such that the congruence lattice of L is isomorphic to D, and L satisfies the properties (P) and (Q) where (P) Every join-irreducible congruence of L we introduce a very simple kind of chopped lattices.

Keywords
we prove that the ideal lattice of this chopped lattice is uniform.
