Implicative-orthomodular algebras

Starting from involutive BE algebras, we redefine the orthomodular algebras, by introducing the notion of implicative-orthomodular algebras. We investigate properties of implicative-orthomodular algebras, and give characterizations of these algebras. Then we define and study the notions of filters and deductive systems, and characterize certain classes of filters. Furthermore, we introduce and characterize the commutative deductive systems in implicative-orthomodular algebras. We also show that any deductive system determines a congruence, and conversely, for any congruence we can define a deductive system in an implicative-orthomodular algebra. We define the quotient implicative-orthomodular algebra with respect to the congruence induced by a deductive system, and prove that a deductive system is commutative if and only if all deductive systems of the corresponding quotient algebra are commutative.
