Genre/Form: Electronic books: Additional Physical Format: Print version: Rose, Henry, Nonmodular lattice varieties / Material Type: Document, Internet resource. The aim of this monograph is to present the main results about modular and nonmodular varieties, equational bases and the amalgamation property in a uniform way.
The first chapter covers preliminaries that make the material accessible to anyone who has had an introductory course in universal algebra. The study of lattice varieties is a field that has experienced rapid growth in the last 30 years, but many of the interesting and deep results discovered in that period have so far only appeared in research papers.

Among the results discussed there. This book presents the foundations of a general theory of algebras. Often called “universal algebra”, this theory provides a common framework for all algebraic systems, including groups, rings, modules, fields, and lattices.
Each chapter is replete with useful illustrations and exercises that solidify the reader's understanding.

Lattice varieties •. Let e be a set of lattice (equations), and denote by Mode the class of all lattices that satisfy every identity in e. A class 1J of lattices is a lattice variety if 1J =Mode for some set of lattice identities e.
The class of all lattices, which we will denote by.C, is. In the branch of mathematics known as order theory, a semimodular lattice, is a lattice that satisfies the following condition. Semimodular law a ∧ b. Note that the lattice reduct of L * is in the variety generated by L, since lattice varieties are closed under the operation of ordinal sum and adding a top element.
If we take L to be M 3, the 5-element modular lattice, then L * is a 3-generated modular, nondistributive, cancellative, integral residuated lattice. Cet article présente la construction de nombreux treillis semi-modulaires au moyen du produit tensoriel de demi-treillis.

Varieties of Lattices Variety is the spice of life. A lattice equation is an expression p ≈ q where p and q are lattice terms. Our intuitive notion of what it means for a lattice L to satisfy p ≈ q is that p(x 1,x n) = q(x 1,x n) whenever elements of L are substituted for the vari-ables.

In the branch of mathematics called order theory, a modular lattice is a lattice that satisfies the following self-dual condition. Modular law a ≤ b implies a ∨ (x ∧ b) = (a ∨ x) ∧ b for every x. where ≤ is the partial order, and ∨ and ∧ (called join and meet respectively) are the operations of the lattice.
This phrasing emphasizes an interpretation in terms of projection. A lattice $(L,\leq)$ is said to be modular when $$ (\forall x,a,b\in L)\quad x \leq b \implies x \vee (a \wedge b) = (x \vee a) \wedge b, $$ where $\vee$ is the join operation, and $\wedge$ is the meet operation.
(Join and meet.)The ideals of a ring form a modular lattice. So do submodules of a module. These facts are easy to prove, but I have never seen any striking examples of their utility.
Vol. 52, Minimal varieties of residuated lattices Proposition Let a be a non-identity element of a strictly simple, lower-bounded residuated lattice A,andlett be a unary term such that A satisﬁes t(x)=a, for all x ∈ A, x =the variety generated by A is an atom in the subvariety lattice.
The lattice career pursues continued growth, development and organizational influence by creating and valuing career paths that move laterally, diagonally and down, as well as up.

We prove that the Leech lattice is the unique densest lattice in R^ The proof combines human reasoning with computer verification of the properties of certain explicit polynomials. We furthermore prove that no sphere packing in R^24 can exceed the Leech lattice's density by a factor of more than 1+*10^(), and we give a new proof that E_8 is the unique densest lattice in R^ by:
