(algebra, order theory) any lattice (type of partially ordered set) that has both a greatest and a least element
Usage notes
The greatest element is usually denoted 1 and serves as the identity element of the meet operation, ∧. The least elem∨ent, usually denoted 0, serves as the identity element of the join operation, ∨. The notations ⊤ and ⊥ are also used, less often, for greatest and least element respectively.
A bounded lattice may be defined formally
as a tuple (L, ∨, ∧, 0, 1).
