Cubic Extensions
Birkhäuser Boston eBooks · 2007
In this chapter, for a finite lattice K , we introduce an extension Cube K with the following properties: (i) The lattice K is a congruence-reflecting sublattice of Cube K . (ii) Con(Cube K ) is boolean. (iii) The minimal extension of the meet-irreducible congruences are the dual atoms of Con(Cube K ); their ordering is “flattened.”
