## distributive lattice

(mathematics)
A lattice in which “greatest lower bound” obeys a distributive law with respect to “least upper bound,” and vice versa.

## distributive lattice

(theory)
A lattice for which the least upper bound (lub) and greatest lower bound (glb) operators distribute over one another so that

a lub (b glb c) == (a lub c) glb (a lub b)

and vice versa.

("lub" and "glb" are written in LateX as \sqcup and \sqcap).
