In mathematics, an Ockham algebra is a bounded distributive lattice with a dual endomorphism. They were introduced by Berman (1977), and were named after William of Ockham by Urquhart (1979). Ockham algebras form a variety.
Examples of Ockham algebras include Boolean algebras, De Morgan algebras, Stone algebras, and Kleene algebras.
