By J onsson's Lemma, the variety VK generated by a nite lattice has only nitely many subvarieties. This led to the conjecture that, conversely, if a lattice variety has only nitely many subvarieties, then it is generated by a nite lattice. A stronger form of the conjecture states that a nitely generated variety VK has only nitely many c o v ers in the lattice of lattice varieties, and that each of these is also generated by a nite lattice. Initial investigations near the bottom of supported… CONTINUE READING
