In Abstract Algebra
The relation of divisibility turns the set of non-negative integers into a partially ordered set, in fact into a complete distributive lattice. The largest element of this lattice is 0 and the smallest is 1. The meet operation ^ is given by the greatest common divisor and the join operation v by the least common multiple. This lattice is isomorphic to the dual of the lattice of subgroups of the infinite cyclic group .

Famous quotes containing the words abstract and/or algebra:
“The Germans are always too late. They are late, like music, which is always the last of the arts to express a world condition,—when that world condition is already in its final stages. They are abstract and mystical.”
—Thomas Mann (1875–1955)
“Poetry has become the higher algebra of metaphors.”
—José Ortega Y Gasset (1883–1955)
