Arts and design

Latticework __NOTOC__ Latticework is an openwork framework consisting of a criss-crossed pattern of strips of building material, typically wood or metal. The design is created by crossing the strips to form a grid or weave. Latticework may be functional &nd ...

, an ornamental criss-crossed framework, an arrangement of crossing laths or other thin strips of material * Lattice (music), an organized grid model of pitch ratios * Lattice (pastry), an ornamental pattern of crossing strips of pastry

Companies

* Lattice Engines, a technology company specializing in business applications for marketing and sales * Lattice Group, a former British gas transmission business * Lattice Semiconductor, a US-based integrated circuit manufacturer

Science, technology, and mathematics

Mathematics

Lattice (group) In geometry and group theory, a lattice in the real coordinate space \mathbb^n is an infinite set of points in this space with the properties that coordinate-wise addition or subtraction of two points in the lattice produces another lattice po ...

, a repeating arrangement of points **

Lattice (discrete subgroup) In Lie theory and related areas of mathematics, a lattice in a locally compact group is a discrete subgroup with the property that the quotient space has finite invariant measure. In the special case of subgroups of R''n'', this amounts t ...

, a discrete subgroup of a topological group whose quotient carries an invariant finite Borel measure ** Lattice (module), a module over a ring that is embedded in a vector space over a field ** Lattice graph, a graph that can be drawn within a repeating arrangement of points **

Lattice-based cryptography Lattice-based cryptography is the generic term for constructions of cryptographic primitives that involve lattices, either in the construction itself or in the security proof. Lattice-based constructions support important standards of post-quant ...

, encryption systems based on repeating arrangements of points *

Lattice (order) A lattice is an abstract structure studied in the mathematical subdisciplines of order theory and abstract algebra. It consists of a partially ordered set in which every pair of elements has a unique supremum (also called a least upper boun ...

, a partially ordered set with unique least upper bounds and greatest lower bounds **

Lattice-based access control In computer security, lattice-based access control (LBAC) is a complex access control model based on the interaction between any combination of objects (such as resources, computers, and applications) and subjects (such as individuals, groups or o ...

, computer security systems based on partially ordered access privileges ** Skew lattice, a non-commutative generalization of order-theoretic lattices * Lattice multiplication, a multiplication algorithm suitable for hand calculation

* Bethe lattice, a regular infinite tree structure used in statistical mechanics * Bravais lattice, a repetitive arrangement of atoms * Lattice C, a compiler for the C programming language * Lattice mast, a type of observation mast common on major warships in the early 20th century *

Lattice model (physics) In mathematical physics, a lattice model is a mathematical model of a physical system that is defined on a lattice, as opposed to a continuum, such as the continuum of space or spacetime. Lattice models originally occurred in the context of c ...

, a model defined not on a continuum, but on a grid *

Lattice tower A lattice tower or truss tower is a freestanding vertical latticework, framework tower. This construction is widely used in transmission towers carrying high-voltage electric power lines, in radio masts and towers (a self-radiating tower or as a ...
