Download or read book Nonmodular Lattice Varieties written by Henry Rose and published by American Mathematical Soc.. This book was released on 1984 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is shown that there are eight infinite sequences of join irreducible lattice varieties with the following properties: each term of every sequence has the next term as its unique join irreducible cover. The description of these sequences is based on a detailed study of subdirectly irreducible lattices with the unique critical quotients.
