Free Universal Algebras

Let be any set, let be an algebraic structure of type generated by . Let the underlying set of this algebraic structure, sometimes called universe, be, and let be a function. We say that, (or informally just ) is a free algebra (of type ) on the set of free generators if, for every algebra of type and function, where is a universe of, there exists a unique homomorphism such that .

Famous quotes containing the words free and/or universal:

    Free from debt is free from care.
    Chinese proverb.

    The axioms of physics translate the laws of ethics.

These propositions have a much more extensive and universal sense when applied to human life, than when confined to technical use.
    Ralph Waldo Emerson (1803–1882)
