Characterizable classes of lattices
Zh. A. Omarov
Abstract:
We look at the concept of a characterizable class of systems. It is proved that there exist characterizable varieties of lattices whose join in the lattice of all lattice varieties is not a characterizable variety. We point out two finitely characterizable lattice quasivarieties, which are not varieties, whose meet in the lattice of lattice quasivarieties is a variety. Also an example of a characterizable locally finite lattice variety is constructed.
Keywords:
characterizable class of lattices, variety.
