Separation properties in congruence lattices of lattices

Miroslav Ploščica (2000)

Colloquium Mathematicae

Similarity:

We investigate the congruence lattices of lattices in the varieties n . Our approach is to represent congruences by open sets of suitable topological spaces. We introduce some special separation properties and show that for different n the lattices in n have different congruence lattices.
