(theory) | lattice - A partially ordered set in which all finite subsets
have a least upper bound and greatest lower bound. This definition has been standard at least since the 1930s and probably since Dedekind worked on lattice theory in the 19th century; though he may not have used that name. See also complete lattice, domain theory. |
