Definitions Submit/More Info Add a definition

  1. A complete lattice is a partially ordered set in which all subsets have both a supremum (join) and an infimum (meet).
  2. A complete lattice is a poset in which arbitrary (possibly infinite) joins (suprema) and meets (infima) exist. Move Up
  3. Any complete lattice (also see below) is a (rather specific) bounded lattice. Move Up
  4. Every complete lattice is also a bounded lattice, which is to say that is has a greatest and least element. (Web site) Move Up

Algebraic Lattice Submit/More Info Add phrase and link

  1. An algebraic lattice is a complete lattice that is algebraic as a poset.

Complete Semilattice Move Up Add phrase and link

  1. Every poset that is a complete semilattice is also a complete lattice. (Web site)

Particular Move Up Add phrase and link

  1. In particular, every complete lattice is a bounded lattice. (Web site)

Finite Set Move Up Add phrase and link

  1. Moreover, every lattice with a finite set is a complete lattice.

Convex Sets Move Up Add phrase and link

  1. The intersection of any collection of convex sets is itself convex, so the convex subsets of a (real or complex) vector space form a complete lattice. (Web site)

Fixed Points Move Up Add phrase and link

  1. An example is the Knaster-Tarski theorem, which states that the set of fixed points of a monotone function on a complete lattice is again a complete lattice.

Complete Boolean Algebra Move Up Add phrase and link

  1. A complete Boolean algebra is a Boolean algebra that is a complete lattice. (Web site)
  2. Notable special usages of the term include the concepts of complete Boolean algebra, complete lattice, and complete partial order (cpo). Move Up

Complete Heyting Algebra Move Up Add phrase and link

  1. In fact, the set of open set s provides a classical example of a complete lattice, more precisely a complete Heyting algebra (or " frame " or " locale "). (Web site)

Set Move Up Add phrase and link

  1. A totally ordered set (with its order topology) which is a complete lattice is compact. (Web site)
  2. More generally, these definitions make sense in any partially ordered set, provided the suprema and infima exist, such as in a complete lattice. (Web site) Move Up
  3. The set of all topologies on a set X together with the partial ordering relation ⊆ forms a complete lattice. (Web site) Move Up

Partial Order Move Up Add phrase and link

  1. The relation of "being-finer-than" is a partial order on the set of all partitions of the set X, and indeed even a complete lattice.

Subset Move Up Add phrase and link

  1. Let X be a complete lattice, then a function f: X → X is continuous if, for each subset Y of X, we have sup f(Y) = f(sup Y).

Closure Operator Move Up Add phrase and link

  1. If P is a complete lattice, then a subset A of P is the set of closed elements for some closure operator on P if and only if A is a Moore family on P, i.e. (Web site)
  2. In summary, one can say that every complete lattice is isomorphic to the image of a closure operator on a powerset lattice. (Web site) Move Up

Heyting Algebra Move Up Add phrase and link

  1. A complete Heyting algebra is a Heyting algebra that is a complete lattice. (Web site)

Lattice Move Up Add phrase and link

  1. The subgroups of any given group form a complete lattice under inclusion, called the lattice of subgroups. (Web site)
  2. If the order is a meet-semilattice (or even a lattice), then this construction (including the empty filter) actually yields a complete lattice. Move Up
  3. Lattice of topologies The set of all topologies on a set X together with the partial ordering relation ⊆ forms a complete lattice. Move Up

Poset Move Up Add phrase and link

  1. A poset, considered as a small category, is complete (and cocomplete) if and only if it is a complete lattice. (Web site)
  2. Completeness A poset is called a complete lattice if all its subsets have both a join and a meet. Move Up
  3. A continuous lattice is a complete lattice that is continuous as a poset. Move Up

Infimum Move Up Add phrase and link

  1. In mathematics, a complete lattice is a partially ordered set in which all subsets have both a supremum (join) and an infimum (meet).
  2. This order has the desirable property that every subset has a supremum and an infimum: it is a complete lattice. (Web site) Move Up

Complete Lattice Move Up Add phrase and link

  1. It is a totally ordered set and a complete lattice (every subset of the unit interval has a supremum and an infimum). (Web site)
  2. A lattice in which every subset (including infinite ones) has a supremum and an infimum is called a complete lattice. Move Up
  3. As explained in the article on completeness (order theory), any poset for which either all suprema or all infima exist is already a complete lattice. Move Up
