eO-代数簇公理
The variety eO of extended Ockham algebras consists of those algebras (L; ∧,∨, f,k, 0, 1) such that (L; ∧,∨, 0, 1) is a bounded distributive lattice together with a dual endomorphism f on L and an endomorphism k on L such that fk = kf. In this paper we extend Urquhart's theorem to eO-algebras and we are in particular concerned with the subclass e2M of eO-algebras in which f2 = id and k2=id. We show that there are 19 non-equivalent axioms in e2M and then order them by implication.
